Paul Pogba's agent has said Juventus would regret not cashing in on the coveted midfielder, suggesting that Borussia Dortmund's Henrikh Mkhitaryan, whom he also represents, should be his replacement.
Mino Raiola, who described the 21-year-old France international as being "like a Van Gogh painting," said the Turin club were likely to receive offers that would be hard to refuse and should accept one of them.
He told La Gazzetta dello Sport: "My father always said that it's better to sell and then to regret it than not to sell and regret it.
"If you sell Pogba, you've got enough money to build a side that can win the Champions League.
"If you want to keep hold of him, then you've got to build a side strong enough for Pogba to improve in -- but if you don't sell him, you don't have the money to do that. Everybody has got a card in their hand, and it's all about when you play it."
Juventus coach Massimiliano Allegri has said former Manchester United man Pogba is worth 100 million euros, and Raiola has said he believes the club could yet keep him for another season.

"If it's not this year, it will be the year after," Raiola said. "All I want is that whoever wants to buy him really believes in him and pays him the world, and if Paul leaves Juve he does it to go to the very top. He is a [future] Ballon d'Or winner, like [Pavel] Nedved.
"He's the only star player available to buy this summer and, if somebody wants him, just you watch how the market drives the value above 100 million. If you can't get [Cristiano] Ronaldo, [Lionel] Messi or [Zlatan] Ibrahimovic, then you can only get him."
Raiola said Mkhitaryan was one player on whom Juve could spend cash from any Pogba sale.
"The feeling between him and Dortmund has broken down," he said. "Then there is [Memphis] Depay and Felipe Anderson, Rodrigo Ely, who is sensational, [Ricardo] Kischna from Ajax, who would be perfect. There is [Jetro] Willems from PSV, then certainly [Marco] Verratti in the midfield."
