Arsenal boss Arsene Wenger says Theo Walcott has "improved tremendously" over the last 12 months.

Wenger claims this Arsenal team is a different animal and insists Walcott now has what it takes to make Barcelona pay.

He said: "Theo has improved tremendously as a footballer. He is completely different now in his link-up play with other players.

"His movement is sharper. He is less nervous, more relaxed. In the last six months he has taken a huge step forward.

"He has improved tremendously and he is now a regular player in our team. That has played a big part for him.

"I think Barcelona are the best club side I've ever come up against. I don't deny they are one of the best ever.

"But we want to show how good we are. We are determined. We want to win this competition.

"We face the super-favourites and the only way to do it is to knock them out."
