The Gunners take on Luis Enrique's men at the Emirates Stadium in the first leg on Tuesday night, and with Arsene Wenger claiming Wilshere is "three or four weeks" away from a return from a broken leg, he may yet play a part at the Nou Camp
Wilshere told BT Sport 2: "It is possible, I mean it's difficult to get back.
"The Premier League gets quicker and quicker and I know I'm not old but I'm different from when I was 19, it takes a little bit more time.
"But I'm training and running and hopefully I will be back.
"I'm not sure how long it's going to take because I've only been doing ball work for about a week
I probably need a game in the under-21s and I'll be ready."
