Napoli coach Maurizio Sarri was delighted with their rout of Cagliari.

Dries Mertens hit a hat-trick as they won 5-0 in Sardinia.

“It was a difficult game because we were coming off a Champions League decider, which takes away a lot of physical and psychological energy. It was also tricky to play with such an early kick-off," Sarri told Sky Sport Italia.

“Cagliari have always done very well at home, but we played a great game and showed real hard work to sacrifice ourselves in defence too. The work of the strikers off the ball makes the difference.

“Now we must try to focus and take the same approach against Torino next week."

Mertens was used as a False 9 and bagged a hat-trick, so is this his ideal position?

“Mertens is a great player who can make the difference as a winger or a centre-forward, so frankly he's great regardless of his role. At this moment I'd talk more about his form, because moving him by 10 metres isn't going to change much."
