From England: Two Premier League sides want Mertens
The Belgian has been one of Napoli's most important players in the Serie A over the last 3-4 seasons. After being initially used as a winger, Mertens became a striker under Maurizio Sarri and has carried it forward since then.
Daily Express in England link Manchester United and Chelsea with a move for the Belgian, whose current deal runs out in the summer of 2020 and Napoli are yet to initiate concrete talks for the former PSV man.
