Napoli striker Dries Mertens is back on the radars of Europe's biggest clubs.

Having raced to eight goals already this season, the Belgium international's form has attracted interest from PSG, Manchester United and Liverpool, says Calciomercato.com.

Mertens' ability to fit into an attacking three suits the systems of all three clubs.

Napoli coach Carlo Ancelotti would be prepared to lose the experienced forward in January - particularly with president Aurelio de Laurentiis openly discussing the prospect of re-signing Edinson Cavani from PSG.

“I'm happy in Italy and I'm fine at Napoli, but maybe in the future I could come to England," Mertens said last season.
