Meanwhile, Mertens would be interested in a move to the Premier League, his agent has claimed.

“If I think about a good opportunity in the market, it would be Mertens from Napoli,” said Mertens’ agent, Federico Pastorello. “He is out of contract [in the summer].

“He is an amazing player. I think he will be soon the best scorer in the history of the club.

“Every player really wants to play in the Premier League at least once. So I think he would be very happy to play in the Premier League.

“I know him very well tactically and technically and I think he can be a successful player for the Premier League.”
