"It's disappointing to miss any game but, if I think about it another way, maybe it will be good for me to have a little break and come back for the Tottenham game (a week later).
"It's a long season so I need to take it easy a bit but I am looking forward.
"Last night (Tuesday), I felt better than I did over the weekend and the weekend before that, so I am feeling better after each game."
Regarding his injury-enforced lay-off, Wilshere added: "I'd had a good season and was looking to push on so to have a setback like that was heartbreaking, but now I'm back.
"I am still doing my maintenance work in the gym and am keeping fit. Every day I need to work hard and get back up to the level I was at."
