Samuel Umtiti's performances this year for Barcelona have alerted a number of Premier League clubs to his contract situation.
It's been reported that the 24-year-old has a £50m release clause in his contract at the Camp Nou, which he signed almost 18 months ago when he completed a €25m move there from Lyon.
The Frenchman has featured in 12 league games for the La Liga leaders this term, missing the last three through injury, but has still managed to catch the eye of clubs from overseas.
Umtiti represented France in their EURO 2016 campaign, and was part of the side that lost in extra-time to Portugal in the final.
He has so far represented his country 14 times, scoring one goal, in a 3-2 victory against England earlier this year.
And the future looks bright for the young central defender, particularly because the release clause in his contract is seemingly a steal at £50m, with Barcelona worried they could lose him.
It would be even more damaging if it was to a familiar face, and according to the Sun, their ex-manager Pep Guardiola set to make a move to bring him to Manchester City.
Guardiola wants to bolster his squad, as he targets an unprecedented quadruple with Manchester City, who can extend their lead at the top to 16 points with victory at Crystal Palace today.
He's losing faith with Vincent Kompany, who again went off injured in the win at Newcastle, while John Stones has missed several matches himself.
It's meant a recall for Eliaquim Mangala, who quite clearly isn't up to the job if City are serious about winning all four major honours.
If the Citizens can secure one of Barcelona's most important first-team members, it would mark yet another important point in their quest to conquer Europe.
However, rivals Manchester United are also interested in Umtiti, so we could be set for a January tug-of-war to secure his signature.
