Manchester City, Manchester United, Juventus and PSG are all interested in making a move for Bayern Munich winger Douglas Costa, according to Bild.
It is believed that the Brazilian would be available for around €40m (£34.9m).
Midfielder Renato Sanches has also reportedly been told he is “allowed to leave” Bayern Munich.
Such a move would mark an incredible downfall for 19-year-old Renato Sanches, who joined just last year amid interest from Real Madrid and United.
The club paid an initial £28m for him but that fee could jump to £60m with club and country-based add-ons.
Bayern are looking to sell Sanches for around £30m before their initial fee is increased.
Costa, 26, who arrived at the Allianz from Shakhtar for £21m in 2015, has scored just seven goals in all competitions this season.
His current deal runs until 2020 but, according to Bild, he has “no chance” of nailing down a spot in the side.
