Napoli coach Walter Mazzarri is angry with midfielder Walter Gargano.

Mazzarri had to discipline Gargano after he returned late to the pitch in the 3-1 friendly win over Portuguese side Braga.

He told calcionapoli.it: "I demand respect for the rules.

"He arrived some minutes after, and I was looking for him to do the warm-up, but there is no talk of the transfer market. Tomorrow we don't even need a handshake, it's just sometimes you need to point out a player's mistakes."
