Per David Hytner of the Guardian, he said:
"I said many times that [Wilshere’s contract] would be decided in December. I wanted to give him six months not to think about that and see where we go. Do we want to clear it up before the January window? Yes.
“For me, Jack is in the position between wide and completely central, or in that area behind the midfield, because he turns the game forward well, he can chip a little ball and he can pass people on the short space. That’s why I think the [3-4-2-1] system suits him well. He’s a little bit in conflict for a position with Ozil and Sanchez. I consider him as part of the front three.”
The Frenchman also hailed Wilshere's turnaround since the beginning of the campaign:
“Jack was ready to be in the dark at the start of the season and just work hard. He was determined and now he feels he has found that little bit of sharpness which is decided in the first two yards. Since he has been playing for us everybody has started to think in a different way about him.”
The Englishman, who is in the final year of his deal at Arsenal, broke his leg in April while spending last season on loan at Bournemouth, the latest in a long line of injuries that have plagued him throughout his career and prevented him from reaching his considerable potential.
Wilshere has impressed in the limited opportunities he's had this year, though, which have been in the UEFA Europa League and the Carabao Cup for the most part.
Goal's Chris Wheatley showered him with praise after an outstanding performance against Red Star Belgrade:
Indeed, the 25-year-old rolled back the years in that match with impressive drive and creativity in the final third, and he played a key role in Olivier Giroud's stunning overhead kick by turning two defenders with a dribble.
Wilshere has been limited to a single 13-minute cameo in the Premier League, but he even made an instant impact in that as he laid on an assist for Aaron Ramsey as Arsenal beat Everton 5-2.
Wenger now believes he can return to the international stage, per ESPN FC's Mattias Karen:
The midfielder is getting back to full fitness, though he has little chance to prove he can maintain it in the long term before his contract situation is resolved next month, so the Gunners will be taking something of a risk if they offer him a new deal.
He's taking full advantage of the opportunities he's had this year to offer a reminder of what he's capable of, though, and if he can continue to do that it could be worthwhile tying him down amid the likely departures of both Ozil and Alexis Sanchez.
