Barcelona have reportedly rejected a £62m bid from Bayern Munich for Ousmane Dembele.
The Spanish champions are said to be closing in on a move for Atletico Madrid attacker Antoine Griezmann, while Paris Saint-Germain's Neymar has also been linked with a return to Camp Nou.
Barca could reportedly be forced to sell Dembele if they wish to sign both Griezmann and Neymar this summer.
According to Diario Sport, Bayern have seen a £62m bid for the France international rejected, with the Catalan giants keen to recoup the majority of the initial £96m fee that they paid Borussia Dortmund in 2017.
Dembele has scored 18 times and contributed 17 assists in 65 appearances for his current club in all competitions.
Bayern are in the market for at least one new winger this summer following the departures of Arjen Robben and Franck Ribery.
The German champions had been strongly linked with a swoop for Manchester City's Leroy Sane, although it is understood that the attacker wants to stay at the Etihad Stadium.
