The Bulgarian international striker believes that United will win the semi-final tie against The Gunners and reach the final in Rome on 27th May.
"The Arsenal games are going to be great for everybody to watch and I know it is going to be difficult," he has said.
"They are a great team. But we are Manchester United, so I think we are going to win.
"We are determined to defend this trophy and the fact we now have to face another English team makes it a little bit different.
"But we should still be confident."
