Former Arsenal manager George Graham has suggested his old club lack the leadership required to win the Premier League title.
The Gunners were shocked by West Ham United at the Emirates as the Hammers enjoyed a 2-0 away win on Sunday.
And according to Graham, the defeat shows that Arsenal need a leader to influence the team and the outcome of games.
"I was really disappointed and very surprised by Arsenal," Graham told talkSPORT.
"Their pre-season form had been excellent and I thought, 'right, let's go at West Ham.' But it amazed me that after the first 20 minutes, both sides had 50 per cent possession - when does an away team come to the Emirates and get that sort of possession? Very, very rarely.
"I was really surprised Arsenal didn't press the ball and put West Ham under pressure, and maybe that just shows you the lack of leadership at the club.
"I didn't see anyone get a grip of the game.
"Arsenal have some brilliant players, but Ozil was very quiet - you never really saw him - and Santi Cazorla was on the left wing in the first half and he doesn't like laying there.
"You're looking for your big names, your big players, to perform, and they didn't do that yesterday."
