Manchester United are ready to offer £100 million to sign France international Paul Pogba, according to AS.
Real Madrid, Paris Saint-Germain and Manchester City are also interested in the 23-year-old.
Agent Mino Raiola confirmed that he is in constant touch with a number of clubs over the possible transfer of the Juventus midfielder.
"If I think about the amount players are going for, then Paul is undervalued," he said.
"He is underrated in money terms. Pogba is worth the maximum amount that any of the clubs who want him can pay for him.
"To say that he is in demand is an understatement. I have had more than 2,000 phone calls about him – I'm taking more than 20 every day.
"If the right offer for Pogba arrives we will do a deal. Most definitely. We are all gentlemen.
"Pogba admires Real Madrid and Zinedine Zidane. That's very important.
"His price tag is how much a club can pay – and right now I believe it has to be around 120 million euros."
