Arsenal have not won a European trophy since they won the European Cup Winners' Cup - a competition doesn't even exist anymore! - way back in 1994.

So they are certainly to get their hands on the prize. They have even already planned a trophy parade in London on Thursday!

Have they jumped the gun a little?

Well, Chelsea captain Cesar Azpilicueta said he hopes his team can ruin their party plans before they have begun.

"Our job is to play the game and to win the trophy. We didn't plan a parade but that doesn't mean we are not hungry and determined to win the trophy."

Who do you think is going to take the title? Let us know below!
