Aaron Ramsey could be a doubt for Arsenal, ahead of their big clash with Manchester City at the weekend.
He went off injured last night during Wales's 2-1 win over Andorra in their opening Euro 2016 qualifier.
Welsh boss Chris Coleman blamed the artificial pitch and heavy tackles from the opposition for the injury.
It means the midfielder could miss the Gunners’ Premier League clash with City on Saturday at the Emirates.
Gareth Bale was the hero for Wales last night, as he scored twice, including a stunning free kick winner, to give them a 2-1 win against Andorra.
He saved Welsh blushes, after Andorra had taken the lead- their first competitive goal since 2010- from the penalty spot.
Bale’s brace sealed the win, however.
