Arsenal are sweating on the fitness of David Luiz ahead of Norwich’s visit to the Emirates on Wednesday.
Luiz had to come off after 54 minutes of Arsenal’s FA Cup win at Sheffield United on Sunday after damaging his right knee.
It meant an early end to his return from suspension following his red card in Arsenal’s first game after the season’s resumption at Manchester City.
Arsenal’s decision to hand Luiz, 33, a new one-year contract last week may have raised eyebrows in some quarters but he remains a valuable member of the squad to head coach Mikel Arteta.
