Barcelona have set a price for French defender Samuel Umtiti.
The centre-back is a wanted man in the summer, with Manchester United among the clubs interested in his signature.
Spanish publication Sport suggests that if a club offers £46 million, Umtiti can leave.
The Frenchman is regarded as a top class centre-half, but has suffered knee ligament issues in the past 18 months.
And United could be in the market for a defender, especially if they sell Phi Jones, Marcos Rojo and Chris Smalling.
It would leave them with only Harry Maguire, Victor Lindelof and Axel Tuanzebe for two positions.
Arsenal have also been linked with the World Cup winner.
