The father of Dries Mertens will be surprised if he leaves Napoli this summer.

The Belgium international has been linked with Maurizio Sarri's Chelsea.

But his father told Radio Crc: "He is very happy. He is now famous. I was a long time with him in Russia, we did not talk about Napoli, because he focused on the World Cup.

"But unless there are any upheavals, he will stay with Napoli, he has already spoken to (Carlo) Ancelotti. His real goal is to win the title of champion with the club, it would be a party."
