Atletico Madrid want close to £43m if they are to sell Kieran Trippier this summer, according to Sky Sports.
This is coming after Football Insider revealed they rejected a bid of around £10m from Manchester United for the England international.
Atletico, who are the reigning La Liga champions, do not want to sell the 31-year-old who is part of the English national football team at the ongoing Euros.
It is not certain if United are willing to pay £43m for a player who is in his 30s.
United are looking to bolster their side ahead of next season, and according to Sky Sports, they are interested in Norwich right-back, Max Aarons.
