Hernandez signed a six-year deal with his club earlier this summer but United are reportedly interested in the World Cup winner
Atletico Madrid want to raise Lucas Hernandez’s release clause to €150m (£135m) to ward off interest from Manchester United.
The 22-year-old impressed last season in Spain and he was rewarded with a place in France’s World Cup squad.
The left-back cemented his position in the team during the tournament and helped them go on to be crowned champions.
Manchester United are now interested in signing Hernandez this January and they have the funds to do so.
The defender currently has an €80m (£72m) release clause in his contract after committing his future to the club until 2024 and that is within the Old Trafford club’s budget.
But, according to AS, they need to act fast as Atletico are working on increasing that amount.
The Spanish club are in talks with Hernandez about a new deal that would increase his release clause to €150m (£135m).
The France international would also have his wage increased to a level similar to that of Atletico’s best-paid players.
