Arsene Wenger has refused to single out goalkeeper Petr Cech for criticism following Arsenal's 2-0 defeat to West Ham United at the Emirates Stadium.
The Gunners' Premier League campaign began on a sour note as goals in either half from Cheikhou Kouyate and Mauro Zarate gave the visitors all three points.
Cech was arguably at fault for the opener after being beaten to the ball by Kouyate, who headed into an empty net, but Wenger says that none of his players covered themselves in glory.
"I haven't spoken to him yet. I can't see many individual convincing performances today so it's difficult to single someone out," he told the club's official website.
The North Londoners face Crystal Palace away next Sunday.
