The Belgian centre-back believes that Wilshere's display showed that he is "growing and growing".
"I think Jack did well," he told Arsenal's official website. "For him and for Abou [Diaby] it was not easy with 10 men, they had to run a lot. Jack did well and he worked hard.
"You can see that since he came back he is growing and growing. And I think at the moment he is at a good level.
"He is a world-class midfielder and he can only get better because he is young, coming back from more than a year out with injury. So I am very confident he will come back really strong."
Arsenal are currently sixth in the Premier League table.
