Chelsea have made an offer for Napoli striker Dries Mertens.

The 32-year-old is out of contract in the summer and could move to the Premier League.

Corriere dello Sport says Chelsea are determined to bring Mertens to Stamford Bridge and beat their rivals to his signature.

Manchester United and Arsenal are ready to rival Frank Lampard in the race to sign the Napoli ace.

Inter Milan boss Antonio Conte is also keen on Mertens who is the all-time top scorer for his current Serie A side.

Chelsea are desperate to strengthen their side this summer with Olivier Giroud, Pedro and Willian likely to leave the club.
