After becoming the first goalkeeper to save a Mario Balotelli penalty, Napoli's Pepe Reina asked for the striker's shirt - which he now sleeps in.

After saving Mario’s penalty I couldn’t not ask for his shirt. It was a historic event.
He gave me it and I’ve brought it home to create an unusual pair of pyjamas. I sleep with his shirt and Napoli shorts.

Rafa Benitez has described Gunners boss Arsene Wenger as the "top coach" in England ahead of Napoli's trip to Arsenal in the Champions League tonight.
Benitez never managed a victory at Arsenal during his time in charge of Liverpool, losing five and drawing four, although his Champions League win ratio (54%) is better than Arsene Wenger's (46%).
– Napoli manager Rafael Benitez
We are going to play against a top side so we must show character, strength - but we must also show respect to a team that is top of the league and playing very well.
I am expecting a strong team because I think Wenger is the top coach in the Premier League, and then they signed top players so it is going well for them. Arsenal have a great manager and a good team.
