Harry Kane and Jude Bellingham are among seven stars who may be forced to snub England duty because of a major decision.
England kicked off their final preparations for Euro 2024 with a 3-0 win against Bosnia & Herzegovina on Monday, and on Friday Gareth Southgate's side will face Iceland.
Southgate will confirm his final 26-man squad for the tournament on Saturday, with Kane and Bellingham shoe-ins to be included.
However, both may have to snub the Three Lions in 2025 due to the FIFA Club World Cup.

FIFA have completely revamped the tournament, with 32 clubs entering the inaugural expanded version of the CWC taking place in the USA next summer.
However, leagues around the world and player unions have raised serious concerns about player welfare due to the increased game load.
At present the FIFA CWC is scheduled to begin on June 15 and end of July 13, 2025, with over £2 billion in prize money to be split between the participating clubs.
According to The Sun, league bosses want the tournament brought forward by two weeks so that players can have proper summer breaks before beginning pre-season with their clubs.

However, moving the start date of the tournament to the beginning of June would clash with FIFA World Cup Cup qualifiers ahead of the 2026 World Cup in the USA, Mexico and Canada.
With Bayern Munich and Real Madrid among the clubs to have qualified for the CWC, Kane and Bellingham might have to choose between their clubs and country.
Manchester City stars Phil Foden, Kyle Walker, Jack Grealish and John Stones could face a similar dillemma, as could Chelsea attacker Cole Palmer.
There is the possibility that Premier League clubs and player unions decide to boycott the revamped tournament, with Premier League chief Richard Masters, PFA boss Maheta Molango and LaLiga president Javier Tebas all in favour of taking action.
