Manchester United are making millions in sell-on fees from former players moving clubs this summer.
The Red Devils are looking to bolster their own squad after a dismal season last campaign that saw them finish 15th in the Premier League under new head coach Ruben Amorim.
Their season could have been somewhat saved had they won the Europa League, but they lost the final 1-0 against Premier League rivals Tottenham and pressure is now on Amorim to perform.
After branding his United team the 'worst' in the club's history last season, Amorim has been desperate to improve the personnel at his side, with United officials so far backing him in the transfer market.
