Manchester United must beat Chelsea and Newcastle United to the signing of Barcelona defender Jules Kounde this summer.
The Red Devils could make multiple changes to their backline ahead of next season with several players anticipated to head for the exit door.
Centre-back duo Raphael Varane and Jonny Evans have their contracts expiring on June 30 and could be released with no renewal plans in mind.
Meanwhile, right-back Aaron Wan-Bissaka could also be sold in the coming months.
