United are looking to strengthen their defence in the summer and have been linked with a multitude of top stars to fill the void.
Eric Bailly is expected to leave while the form of Phil Jones and Chris Smalling cannot be relied upon.
And it has led to the Red Devils culminating a list of potential targets, including Kalidou Koulibaly, Toby Alderweireld and Jerome Boateng.
But they are expected some intense fight from their respective clubs over their sales and have been warned off several times – but there is one club that are reportedly willing to let their man go.
Barcelona have their eyes set on Ajax sensation Matthijs de Ligt who is regarded as a potential world-class talent.
However, they need to drum up funds after already splurging £65m on his team-mate Frenkie de Jong.
One man Los Cules look ready to offload is centre-back Umtiti, who has fallen behind Clement Lenglet in the pecking order – with the Daily Mail reporting that United are looking to snap him up.
The World Cup winner has frequently been linked with an Old Trafford move but has always stated his dream to stay at Barca.
The Daily Mail have also go on to report that his club team-mates are not happy that his exit is even being entertained.
The former Lyon ace is a popular figure in the dressing room despite losing Ernesto Valverde’s trust.
One major problem for both Barcelona and United, though, is his injury worries.
The 25-year-old has missed three months this season with a cartilage problem in his left knee, which he chose not to get operated on.
Despite his club troubles, Didier Deschamps is still a huge fan of the centre-back.
He is first-choice ahead of Lenglet for France, pairing him with Real Madrid rival Raphael Varane.
Les Bleus have started their UEFA EURO qualifiers in fine fettle, beating Moldova 4-1 and then Iceland 4-0 last night to top their group, which also consists of Albania, Andorra and Turkey.
