Arsenal striker Alexandre Lacazette says they must win the Europa League final.

The Gunners are going to Baku after a comfortable 4-2 victory at Valencia on Thursday night. They reach the final 3-7 on aggregate.

Lacazette said, "We reacted well to going behind and we knew we had to score a minimum of one goal tonight. Auba was unbelievable tonight with an incredible hat-trick, so thanks to him.

"We have played badly in Premier League during the last month and now we have to use this opportunity. We want to play in the Champions League next season and we want the trophy."
