Manchester United target Dries Mertens has reportedly stalled on penning a new deal with Napoli as he is eager to hear what the Red Devils, and fellow suitors Manchester City, have to offer.
According to TalkSport, Napoli have been in prolonged negotiations with the Belgian striker over a new contract, but interest from Manchester has prevented him from signing, and Mertens is interested in a potential move.
Mertens' current deal with the Partenopei only runs to 2018, so Napoli may be forced to cash in on their star man if he does not commit to a longer deal, or else they risk losing him for free at the end of next season.
