The striker proved the difference on Saturday afternoon as he came off the bench to score the only goal of the game in the 1-0 win over Norwich City.
It was the latest positive impact Welbeck has had in the second half of this season, having battled back from a long-term injury lay off.
His performances now beg the question whether he is good enough to lead the Arsenal line and save them money on the striker that many believe the squad is lacking.
Redknapp though, says he is not convinced he can get the goals they need and neither is Wenger.
“I’m not sure he’s a 20-25 goal a year man, is he in the same class as an Aguero?” he told Sky Sports.
“I’m not convinced and Arsene Wenger isn’t either, that’s why he keeps playing him wide left. If he thought he was the answer he’d put him up there.”
“He’s a great team player, he works extremely hard, but is he guaranteeing you goals? I don’t think so. How many of those scruffy goals is he going to get you that the likes of Harry Kane and Sergio Aguero get? “
Unfortunately for Welbeck, it does appear that Wenger does not have the confidence in him to make him his first choice centre forward at the club.
However, with Olivier Giroud and Theo Walcott struggling for goals, he may be forced to concede defeat and give Welbeck his chance to impress.
Whether or not that would be a long-term solution though is debatable, with many still demanding they sign a world-class striker this summer.
