Chelsea are in contact with Napoli striker Dries Mertens.
The Daily Mail says Chelsea have made an enquiry for Mertens as they consider options for their attack.
The 32-year old was expected to leave Napoli in the summer but Chelsea are exploring whether a deal can be done now.
Chelsea want a forward amid Tottenham interest in Olivier Giroud and Tammy Abraham playing through injury.
Like Tottenham, they have been offered Krzysztof Piatek from AC Milan but they want a loan with obligation to buy at around £28million.
Both Premier League sides would prefer a straight loan with an option instead should Piatek impress.
