Manchester United are preparing a massive windfall of £70m ($103.85) for the trio of Mats Hummels, Nathaniel Clyne and Memphis Depay in the summer, according to the Times.

Louis van Gaal is desperate to add more quality to the side so that they can challenge for the title next year and the trio's inclusion would be a massive step in the right direction for the 20-time Champions.

Hummels, who is still thinking over his contract situation, has received backing from manager Jurgen Klopp, who insists that the German is good enough to lead United to further glory.

"He's good enough for Manchester United. He's told me he's thinking things over," Klopp said in an interview.

The manager himself has made his situation clear with the club, stating in a press conference on 15 April that he will be leaving the club after the end of the season. This has made the situation surrounding the future of the players all the more convoluted, especially with the likes of Marco Reus and Ilkay Gundogan also being linked with a myriad of clubs in the summer.

United are also keeping a close eye on Clyne to replace Rafael, who has fallen out of favour with the manager following a series of brash tackles and hotheaded antics on the pitch. Antonio Valencia has been deputised in his place but Van Gaal is looking for more quality in that position and has earmarked the Southampton man to fill the void.

The Red Devils are also close on the heels of PSV Eindoven winger Depay and are believed to have beaten Liverpool for his signature. The Merseyside club were not willing to meet his release clause, which the Red Devils, given their financial stronghold have been more than willing to cover.

Depay has been in brilliant form this season, scoring goals for fun in the league and was also inducted into the Netherlands World Cup squad in 2014 where he has worked under Van Gaal.

United are currently third in the league and have an opportunity to move into second this weekend when they face Chelsea, with Arsenal taking the week off owing to FA Cup reservations.
