Wilshere is the golden boy of the Emirates, but has lost some of his shine this season.
Patchy form, a cigarette scandal and the rise to prominence of Mesut Ozil and Aaron Ramsey in particular have meant that Jack is no longer considered quite the Emirates talisman he had become.
However, after his feats against Marseille, Wenger says that 21-year-old Wilshere is ready to take up the mantle of Arsenal’s heavyweight midfielder again.
"He's coming back to a good level now," Wenger said of Wilshere last night.
"You could see that on Saturday [against Southampton] and again in this game. He has started to score goals and I like what I see from him in this game.
"He is starting to think, 'what Aaron Ramsey can do, I can do'. You can see [against Marseille] that he is free to move in from his position on the flank and he does that in an intelligent way.
"What is most important in a good football team is that many players can score and that many players can get chances. This time it was him [Wilshere] and another time it will be someone else."
For his part, Wilshere was satisfied with a job well done, but is adamant that there is more to come from him this season.
"I played 90 minutes on Saturday, 75 minutes tonight and I'm feeling good at the moment, I'm feeling fit," he told ITV Sport.
"I set myself a target of 10 goals [for the season] and I have four now, so hopefully I get there.
"Overall it was a great win against a good Marseille side. We created a lot of chances tonight, we played great. We and this was a good win at home. We got in behind them, got the two goals and we are happy with a win."
Meanwhile, in the oddest news from the night, Gunners midfielder Mathieu Flamini received a dressing-down from Wenger, for dressing badly.
Flamini likes to cut the sleeves off his shirt before every game, much to the increasing ire of Arsenal’s kit man.
He was warned not to do it again, but took to the field against Marseille with shorn sleeves, and Wenger was livid.
"I do not like that and he will not do that again," he said. "I was surprised he did that; we don't want that."
Flamini later explained himself: "I've been playing at the top level for 10 years," he said. "I like to wear short sleeves, that's what I like to do."
Flamini has been one of Arsenal’s surprise success stories this season, and so you would think Wenger would simply allow him to wear what makes him comfortable on the field.
All eyes on Flamini’s sleeves then, when Arsenal play next.
