But Wilshere is confident Arsenal are capable of maintaining their position at the top of the Premier League as long as Giroud stays fit.
Speaking after Arsenal’s 2-0 win over Fulham on Saturday, Wilshere said: "He's [Berbatov] a great player. He has played for Manchester United. Players who don't have ability don't play for Man United.
"But he is a Fulham player so I can't talk about him. We have Olivier, who has been great for us this season. If we can keep him fit we have a chance.
"People underestimate our squad. We have a lot of talent in there. Look at the bench - Alex Oxlade-Chamberlain plays for England, Podolski, Vermaelen isn't even on there because he's injured.
"We have to rotate sometimes and we do. Mikel comes in and I go out or to the right and that is important. If we are going to win the championship that is what we are going to have to do."
