Arsenal manager Unai Emery says Thursday night's Europa League quarter-final against Napoli will be an even contest.

The Italian side, led by Carlo Ancelotti, will be heading to the Emirates hoping to take a positive result away from home.

Speaking at the pre-match press conference, Emery said: "I think it's 50-50. Napoli have a big history like us, they're second in the table.

"They're playing very well, they came from a strong group in the Champions League. They were very competitive.

"It's going to be difficult for us but we have confidence. We need to be very consistent in two matches."
