Theo Walcott faces another couple of weeks on the sidelines after suffering a set-back in his recovery from an abdominal muscle strain.
The winger was back in training but according to reports had a reaction to the injury while jogging on Thursday.
“He had to stop, to jog again,” said Arsene Wenger. “He is at least two weeks away now.”
The Walcott news is tempered by the return of Santi Cazorla and the 60 minutes he got against Norwich should see him rebuild some of his preternatural sharpness.
Meanwhile, Wenger has praised front-man Olivier Giroud, saying he’s responded well after Arsenal’s very public striker hunt last summer.
“Giroud is amazing because he develops well,” he said. “If you compare his technical level when he arrived to how it is today, he has highly improved. Now he enjoys combining much more.
“From a player who was just thinking ‘I have to score’, he has become a real team player.
“Nobody came in, so you know at the start of the season that at least you get the chance to show how good you are.
“I always thought that his second season would be the decisive one. We have seen that many times – to adapt to the kind of game we play takes time. I was not too worried when we didn’t bring anyone in because I thought he had a chance to develop.”
