Arsenal defender Ben White is set to miss the rest of the season with a knee injury – and is a huge doubt for England's World Cup squad.
White had just returned to the England team for the first time in more than three years, in the recent friendlies against Uruguay and Japan in March, with the defender scoring in the draw against Marcelo Bielsa's side.
It will also be a personal blow to miss out on what could be an historic end to the season for the Gunners with the chance for two trophies just three games away.
White put in an excellent performance in the Champions League second leg against Atletico Madrid and his partnership with Bukayo Saka on Arsenal's right-hand side has flourished since he returned to the side.
Now the worries about the season run-in and who to play right-back will be on the Arsenal manager's mind.
Jurrien Timber is still out with a groin injury and Mikel Arteta played Declan Rice at right-back against West Ham before putting Cristhian Mosquera into that position for the rest of the match.
Mosquera has shown that he has the potential to be an elite defender but at just 21-years-old, it would be a big ask for him to start in a Champions League final against Paris St-Germain's elite attack.
In March, Thomas Tuchel recalled White to the England squad for the first time since the defender left camp at the Qatar 2022 citing "personal reasons".
White has six England caps and scored his first international goal in March after Tuchel introduced him in the second half of a friendly against Uruguay.
