United identify Perisic alternative?

Manchester United have turned their attention to Napoli's Dries Mertens after failing to land Inter Milan's Ivan Perisic.

According to Transfer Market Web, sources in the United Kingdom have revealed that the Old Trafford side are keeping tabs on the attacker.

Mertens was part of the Belgian side that came third at the World Cup in Russia, demonstrating his ability to deliver dangerous crosses from the flanks.

Jose Mourinho is in the market for a winger with Anthony Martial close to an exit from United.

Despite the Napoli man being 31-years-old, the Italian side are said to want 40 million euros for him.

He played in 38 Serie A games last season, scoring 18 goals and assisted 6 times to help Napoli finish second behind Juventus, who have won the last 7 league titles in Italy.

United have already completed the signing of defender Diogo Dalot, midfielder Fred, and goalkeeper Lee Grant.

United will play one more pre-season game against Bayern Munich this weekend before their Premier League opener against Leicester City next week Friday.
