Former Arsenal boss Arsene Wenger believes his old club will test Europa League opponents Napoli.

The two clubs will face off in the quarter-finals.

“I will be an Arsenal supporter on the night of the match with Napoli, just like every other game," Wenger told Il Mattino newspaper.

“I don't need to give Unai Emery any advice. I love Carlo Ancelotti, one of the greatest Coaches of all time, a real maestro on how to work with teams.

“Having said that, Arsenal are a great team and it'll be a very difficult task for Napoli to get past them into the next round."
