Manchester United are waiting in the wings as Barcelona star Samuel Umtiti has delayed signing a new deal with the club due to their break of Financial Fair Play regulations.

Under the stipulations, the Catalan giants, who spent €160m on the signing of Philippe Coutinho from Liverpool in January, are not allowed to pay out on Umtiti’s new deal this season without breaking the rules put in place by FFP.

The French defender's current deal runs to 2021, and despite the longevity in his contract, his €60million release clause has the La Liga leaders worried.

They are looking to raise said clause in a new deal and hope this will ward off any interest in the 24-year-old who has been attracting suitors from across the continent.
