Tony Cottee has suggested Theo Walcott is responsible for his own injury.
Arsenal suffered the worst possible start against Sheffield Wednesday, with both Alex Oxlade-Chamberlain and Theo Walcott substituted with injuries.
Walcott had come off the bench himself, only to leave with a calf injury less than 15 minutes later.
The Gunners never recovered, going 2-0 down at half-time and then conceding again early into the second half.
SkySports pundit Tony Cottee suggested Walcott may have been the architect of his own downfall, arguing his injury may have been because he did not warm up properly.
He told the channel's Soccer Special during the game: "I wonder in terms of his warm-up, whether he was sitting on the bench thinking he's go a night off.
"Has he done his warm up properly? If he's not ready to play you might as well put kids on the bench."
Cottee, who played for West Ham and Everton during his career, also criticised Walcott for trying to play on after getting injured.
He added: "He couldn't hit the ball let alone run. Why he went back on I don't know. You could do more damage."
In fairness to manager Arsene Wenger and Theo Walcott, the injury to Alex Oxlade-Chamberlain will have caught them by surprise, but the insinuation from Cottee is that the England international did not prepare well enough pre-game, as he did not expect to be called upon.
