Arsenal striker Alexandre Lacazette concedes their away form means they must beat Napoli in tonight's Europa League quarterfinal first-leg.

Lacazette is expected to start the game.

"We know we are better at home than we are away, so tomorrow is really important for us," Lacazette said. "We also know we can get a good result away, so both games are going to be important for us.

"Last season we fell just before the final so this time we want to go forward. We have to play well in this game.

"On Sunday we played badly [against Everton], all the team. We didn't do what the coach asked us but we still have confidence.

"We know we're still in the race for the Champions League in the Premier League, but we want to win trophies so we are confident."
