Napoli coach Walter Mazzarri says Khvicha Kvaratskhelia is trying too hard.

Victor Osimhen and Kvaratskhelia both scored in the win against Cagliari.

Mazzarri said: "It is important that Kvara and Osimhen are calm.

"When a boy like him becomes a champion in Naples it changes everything. He would like to overdo it and outdo everyone, he loses energy and is no longer lucid. I'm also happy because Osimhen and Kvara scored again.

"I came to lend a hand to everyone, from the president to the fans. I've already seen something that I can improve and do something different. After a crazy year there was the risk of a more complicated year, even if (Luciano) Spalletti had remained."
