Napoli striker Dries Mertens is warming towards a move to Chelsea.

Off contract in June, the experienced forward is a target for several European giants, including PSG and Inter Milan.

However, Chelsea boss Frank Lampard has been pushing hard to convince Mertens about a move to London - and his approach appears to have won over the Belgian.

Corriere dello Sport says Mertens' admiration for 'legend' Lampard is the reason he will turn down a new deal at Napoli to join Chelsea.

As well as his desire to move to a new league, it is Lampard that is a key factor.
