The striker ends the season with 32 goals and Wilshere told arsenal.com: "He's been exceptional.
"I've said it before but credit to everyone at the club and at Hale End for the work that they have done with him. He's adapted so well, helped the team massively at times. Also, credit to his teammates too because they serve him so well, and he's grateful for that."
Wilshere also said of Harrison Dudziak and Michal Rosiak being promoted to the U21s next season: They've been exceptional in terms of reflecting the Arsenal values, and they live it every single day. It's been tough for them at times seeing other players get called up for the under-21s, but even though they've been in the under-18s, they've remained professional, and they're the glue of the team.
"They've kept the unity there, and I'm happy for them and wish them all the best going into the under-21s next year. I'll miss them."
