A notable example of a dual-qualified player is Scotland's Ben White, who previously represented England Under-20s, highlighting the complexities of international eligibility in rugby.

Bevan Rodd and Ewan Ashman, who pack down together in the Sale front row, have a shared history, having previously played together on the same team.

This past could have continued, with the two potentially lining up together on Saturday at Murrayfield.

In April 2021, England coach Eddie Jones sent forwards coach Matt Proudfoot to meet with Rodd and Ashman at Sale's training ground, aiming to discuss their international aspirations with the then-uncapped players.

Ashman, who started Scotland's opening Six Nations match in Rome but is now injured, has a complex background, having been born in Canada, raised in Manchester, and having a father from Edinburgh.

Rodd, born in Dunoon, Scotland, and raised on the Isle of Man, has English heritage through his father's side of the family, making him eligible to play for either country.

According to rugby's regulations, both Rodd and Ashman are eligible to represent either England or Scotland, due to their respective family ties and places of birth.

Ultimately, the two players chose different paths, with Ashman opting to represent Scotland and Rodd choosing to play for England.

Seven months after Proudfoot's visit, Ashman made his Scotland debut against Australia at Murrayfield, scoring a try, while Rodd made his England debut against the same opponents just six days later.

The choice between representing England or Scotland is a common dilemma for many young players, given the shared history and border between the two countries.

Examples of players who have faced this decision include England wing Tom Roebuck, born in Inverness, and Henry Pollock, whose parents are Scottish, as well as Fin Smith, whose grandfather played for Scotland in the 1950s.

Scotland's Ben White, a prolific try-scorer in the Calcutta Cup, has a notable background, having been born in Stoke, captained England's Under-20s, and even played for them in a non-Test match against the Barbarians.

Other players with complex eligibility include centre Huw Jones, who moved to England as a toddler, and full-back Tom Jordan, who has a grandmother from Blackpool.

The process of securing dual-qualified players is ongoing, with countries competing to "capture" these talents through senior or second-string appearances, a process that begins at a young age.

The upcoming match is scheduled for Saturday, 14th February, at 16:40 GMT.

The venue for the match will be Scottish Gas Murrayfield.

Live commentary of the match will be available on BBC Radio 5 Live, BBC Radio Scotland, BBC Sounds, and the BBC Sport website and app.

Two weeks ago, Scotland's coaching staff made a notable visit to a school in Dorking, just 12 miles from Twickenham, to work with young players who may be eligible to represent Scotland in the future.

The session, held at RGS Surrey Hills school, brought together Under-16 and Under-18 prospects, who ran through drills under the guidance of Scottish Rugby's SQ programme staff.

The SQ programme aims to establish connections with young players who, like Ashman and Rodd, live and play outside of Scotland but may be eligible to represent the country in the future.

The programme's coaches, including English-born former Scotland international Peter Walton, rely on tips from schools and clubs to identify potential players.

They also set up recruiting stations at high-level age-grade rugby events, inviting players with Scottish ancestry to provide their details and learn more about the SQ programme.

All countries strive to maximize their talent pool, with England working to secure players like Junior Kpoku, a winner of the Under-20 Rugby World Cup, and Benhard Janse van Rensburg, who will soon be eligible to play for England.

For countries with smaller talent pools, such as Scotland, which has around 50,000 club players compared to England's 880,000, the importance of securing dual-qualified players is even greater.

The Rugby Football Union's successful review of Janse van Rensburg's eligibility is an example of the efforts made by countries to secure top talents.

With limited player numbers, Scotland must be strategic in its recruitment, making every effort to secure promising young players who may be eligible to represent the country.

So, what factors influence a player's decision when choosing which country to represent?

National pride is a significant consideration, with many players drawn to the idea of representing their country of birth or heritage.

Ashman, for example, was clear about his desire to play for Scotland when speaking to England's coaches in 2021.

However, players may also be torn between different aspects of their identity, making the decision more complex.

Flanker Gary Graham, the son of former Scotland prop George Graham, grew up in Carlisle and initially attended an England training camp, before later making his debut for Scotland.

Graham's journey highlights the complexities of international eligibility, with players often facing difficult choices about which country to represent.

Graham's decision to play for Scotland, despite initially being involved with England, demonstrates the importance of national pride and personal identity in a player's choice.

Other factors, such as financial considerations, can also play a role in a player's decision.

England's top players can earn significant amounts, with central contracts worth over £150,000 per year, compared to Scotland's match fees of around £5,000 per Test.

However, players may also consider the potential for international appearances and the likelihood of being "captured" by a country, with Scotland's smaller player pool potentially offering a more direct route to the Test stage.

This calculation can be crucial, as players weigh the potential benefits of representing one country over another.

Scotland's smaller talent pool may be a disadvantage in some respects, but it can also provide opportunities for players to progress more quickly to the international stage.

The example of Ruaridh McConnochie, who won two caps for England in 2019 but was later discarded, highlights the risks of being part of a larger talent pool, and the potential benefits of representing a country with fewer players.

McConnochie's decision to switch to Scotland later in his career may have been influenced by the desire for more international opportunities, demonstrating the complex factors at play in a player's choice of country.

In Scotland, a key selling point for prospects is the close alignment and communication between the senior national team, second-string team, age-grade teams, and the country's two professional clubs, all under the guidance of Gregor Townsend.

The decisions players make at the international level can have a significant impact on their club careers, creating a ripple effect that can influence their future prospects.

Ben Vellacott, who has represented Scotland at the age-grade level, declined an invitation to join Townsend's senior squad in 2018, opting instead to attend an England training camp.

In a 2021 interview with BBC Sport, Vellacott explained that his decision was motivated by practical considerations, stating, "As much as I wanted to play for Scotland, I had to be careful I wasn't without a job."

At the time, Vellacott was nearing the end of his contract with Gloucester, and the English Premiership's rules requiring clubs to meet a quota of English-qualified players meant that playing for Scotland would have made him a less attractive signing for English clubs.

Vellacott cautioned that players must be mindful of the potential consequences of their decisions, saying, "You have got to be careful."

He added, "You can play once or twice for your country, struggle to pick up a contract, and then slip down the pecking order," highlighting the risks of prioritizing international ambitions over club career stability.

Vellacott ultimately joined Edinburgh and made his Scotland debut in the 2022 Six Nations, a decision that allowed him to balance his international and club ambitions.

In a separate development, attention turns to the fitness regime of a veteran fly-half, who at 32, is using innovative methods to stay competitive.

Meanwhile, Scotland has made four changes to their team ahead of their crucial match against England, which has been billed as the biggest game of the season.

England has also made changes, with captain Itoje returning to the starting XV to face Scotland.

Interestingly, England's selection policies can sometimes drive talent towards Scotland, creating an unexpected dynamic in the cross-border rivalry.

While Steve Borthwick is limited to selecting players from English clubs, Townsend has the freedom to choose players from any club, giving Scotland an advantage in terms of recruitment.

Unlike their English counterparts, Scotland internationals do not have to choose between representing their country and pursuing opportunities abroad, allowing them to balance their international and club careers.

For example, a Scottish player like White can take up a contract with a French club like Toulon and still remain part of Scotland's plans, a flexibility that is not available to English players.

For younger players, educational opportunities can be a significant factor, with English Premiership clubs' partnerships with top schools and universities attracting talent from across the border.

The influence of Scottish rugby at Newcastle, a club backed by a major energy drink brand, is a development worth watching, particularly given the involvement of key Scottish figures.

Townsend is working as a part-time consultant at the club, which has also appointed his former Scotland teammate Jonny Petrie as managing director and fellow Scot Neil McIlory as general manager.

Gavin Vaughan, Scotland's chief analyst, is reportedly set to join the club as head of recruitment after the Six Nations, further strengthening the Scottish connection.

Newcastle has recently signed several Scottish-qualified players, including George Turner and Elliot Millar Mills, who are both part of Scotland's matchday squad.

The question on everyone's mind is whether Newcastle can become a hub for Scottish-qualified talent in England.

Only time will tell if this vision becomes a reality.

One thing is certain, however.

The increased residency period for players to qualify for a nation, which was extended from three to five years in 2021, has made it more challenging for clubs to invest in "project" players.

With the new residency rules in place, it no longer makes sense for clubs to invest time and resources in players who may only be available for a single Rugby World Cup cycle.

As a result, the competition for talent with immediate international credentials has intensified, with clubs and countries vying for the best players.
