Forward Mesut Ozil believes he is being made the scapegoat for Arsenal's problems, according to his agent.
Ozil, 28, was criticised again after Arsenal suffered a 5-1 defeat at Bayern Munich in Wednesday's Champions League last-16 first leg.
"Criticism is normal if a player plays badly," Dr Erkut Sogut told BBC Sport.
"But Mesut feels people are not focusing on his performance; they are using him as a scapegoat for the team after bad results."
Ozil joined Arsenal from Real Madrid in 2013 for a club-record £42.4m, and came with a reputation as one of the game's leading playmakers.
