The Arsenal boss has confessed that the attacker’s recovery has taken longer than expected.
The England international is on the sidelines and missed his side’s 2-0 home defeat against West Ham at the Emirates Stadium last weekend.
Welbeck is still expected to be unavailable for the next couple of weeks, with a slow start to the campaign for the former Manchester United forward.
Wenger has given an update on the versatile player’s condition and stated that the English star would not need to undergo surgery.
“It is much slower than expected,” Wenger is quoted as saying by The Guardian.
“It was a bone bruising at the start. You think that it will be quite quick. He is an important player for us and the fact that he is not available is a bit of a concern.
“It is bone bruising and nothing wrong at all. They have done all kinds of scans that today are very sophisticated and some of them I don’t understand at all. But they tell me (there is) no (need for surgery).”
Welbeck’s first season with the North London club was hot-and-cold, with the versatile forward scoring some important goals for his side and putting in a number of strong performances, but being used in a squad rotation system.
The ex-United attacker has revealed that he wants to play as a centre forward, but Olivier Giroud continues to dominate the furthest player forward position for the Gunners.
As such, Welbeck has the likes of Theo Walcott, Alexis Sanchez and Aaron Ramsey as competition for a berth on one of the flanks.
