Tottenham Hotspurs star Kieran Trippier is set to leave the London club after several European clubs expressed interest to sign the England right-back.
Trippier has endured a difficult season after a sparkling World Cup with England and is reportedly free to leave once the transfer window opens.
Atletico Madrid are willing to pay around £15million for the right-back, but Spurs want to hold out for closer to £40million.
Even by his own admission, the 28-year-old has had a below-par season and Mauricio Pochettino is reportedly planning a big reshuffle of his squad.
Manchester United and Everton are keen on keeping the former Burnley star in the Premier League, despite his poor form.
However, Serie A side Napoli are also keen on luring the World Cup semi-finalist away from the Tottenham Hotspur Stadium.
Reports in Italy suggest boss Carol Ancelotti is reluctant to engage in a bidding war – especially if Spurs stand firm on the £40million transfer valuation.
United are keeping tabs on Trippier, but also have Crystal Palace wonderkid Aaron Wan-Bissaka in their sights.
The England Under-21 international has enjoyed a sterling season at Selhurst Park and Ole Gunnar Solskjaer could try to bring the 21-year-old to Old Trafford.
