Yamal a doubt for Valencia as fitness concerns mount

The young Spanish international returned from international duty carrying back discomfort, having featured in World Cup qualifiers against Bulgaria and Turkey despite the problems.

His absence has raised concerns ahead of the match as Lamine Yamal is one of the side's most influential players, capable of turning games on his own.

Manager Hansi Flick is expected to provide an update on the player's condition during the pre-match press conference, with the club doing everything possible to have him available.

Meanwhile, Frenkie de Jong, who sat out Friday's session, returned to training on Saturday and is expected to be included in the squad for the Valencia game, barring any late setbacks.
