Real Madrid manager, Zinedine Zidane, has admitted that they are also keen on signing Paul Pogba.
Manchester United have been negotiating for the France mifielder for weeks now, but no deal has been agreed yet.
Juventus have already rejected an intial bid of £86m from United, but the Old Trafford club are looking to increase their offer.
However, the deal may now be in danger, as Madrid confirm interest in the 23-year-old.
Zidane said: “I don’t know if he will come. Until the 31st of August anything can happen. Everyone is interested in Pogba.
“He’s a great footballer and when you are Madrid you always want the best players.
“But now he’s not a Real Madrid player, he’s a Juventus player. I can’t say anything more.”
