MANCHESTER UNITED and Arsenal have been put on red alert with Napoli star Dries Mertens’ release clause being put at just £25million, according to reports.
Stadio San Paolo chairman Aurelio De Laurentiis has made sorting the forward’s contract a top priority.
Mertens’ camp and the club have been locked in contract negotiations for a while, claim calciomercato.
The Belgium star’s current deal expires in 2020 and the Serie A side, so impressive under Maurizio Sarri, are desperate to tie him down.
But no agreement has yet been reached and that keeps the door to a Premier League move open.
Mertens’ release clause of £25m is well under the going rate for a top class forward – with big names being touted around the £100m mark.
Mertens represents a bargain for a player of such quality who has bagged 17 goals and six assists in the league this season.
Napoli are said to be desperate to modify this amount with Premier League sides interested in the 30-year-old.
The Light Blues are looking to hand the striker a new £3.5m-a-year contract.
However, matters are complicated further by Napoli’s 3-0 defeat to Fiorentina last weekend.
That looks to have gifted the league title to Juventus – who Sarri’s side actually beat in their previous fixture.
It is thought Mertens could be looking for a new challenge, with some thinking Napoli have gone as far as they can.
Mertens previously labelled himself a “bargain” for United and Chelsea.
