Napoli striker Dries Mertens has put Chelsea boss Maurizio Sarri on notice.

Mertens played for Sarri for three seasons at Napoli, developing into one of the feared strikers in Europe.

Now the Belgian has hinted he could be reunited with Sarri at Chelsea in the future.

“I love it here [at Napoli] but maybe in one year, I'm free [from my contract], so maybe you never know, maybe Sarri is going to call me," he told The Times.

"We will see."
