The 56-year-old former Republic of Ireland midfielder told TalkSPORT: "We were all a bit nervous - it was 18 months (out injured) - but he has improved with every game and his performance against Liverpool was outstanding.
"I think he will be up there with the very, very skilful creative English players. In my time it was Glenn Hoddle, (Paul) Gascoigne came after that and then (Wayne) Rooney and I think Wilshere will be in that mix.
"I think he is leading the (Arsenal) team now, his pace is deceptive. He has a funny running style but he drifts past players, and he's only 22 (sic), he's only going to get better."
