Wenger handed a rare start to Wilshere and the England global looked sharp in midfield, dictating most of Arsenal's attacks.
When pressed for his thoughts on the 28-year-old, he said: "It's hard to say that [he is in a dip], he has tried tonight".
On Wilshere's performance, Wenger told BT Sport: 'Overall it was a positive performance. "Especially in first half".
'He showed good acceleration, he got fouled a few times and contributed very well.
Former Arsenal defender Martin Keown believes Arsene Wenger's days with the Gunners are now very much numbered. Masuaku was also praised by experts after the game for his impressive performance, providing pace and flair down the left wing.
But on the whole, Wenger felt frustrated with how the match went, particularly regarding West Ham's willingness to sit back.

Speaking on the Alan Brazil Sports Breakfast, Curbishley said: "Against Man City and Chelsea, they had a plan".
"They focused on defending and didn't try to come out at all". Past year we got done here by the so-called bigger teams by three or four so to keep two clean sheets [and get] four points is a great reward.
The Hammers have plenty of survival hope and since the arrival of Moyes - and the installation of Adrian in goal, have looked a much better outfit - who of course picked up a massive three points against Chelsea on the weekend to go towards their survival hopes and put the final nail in Chelsea's hopes of retaining their title this season.
"When I saw the fixtures when I took the job I thought "oh no", Moyes said.
"Against the better teams we've tried to make sure we don't concede, the other games might give us more chances to be on the front foot".
'It sat up a little bit but I should have hit the target and probably won us the game'.
