RB Leipzig have admitted they will continue to sell their best players amid Manchester United's admiration of Dayot Upamecano.

The 22-year-old centre-back has attracted attention from a string of top European clubs and the MEN understands United want to sign a new central defender this year.

United scouted centre-back Upamecano, 22, when he was a teenager but decided against moving for the France international. Upamecano is contracted to Leipzig until 2023 but has a reputed €42million release clause and is expected to leave this year.
