The Fiorentina winger impressed at the World Cup with Colombia and is reportedly a target for Barcelona, though the Manchester United manager is wary of making "the price rise"
The manager has sanctioned the arrivals of Luke Shaw and Ander Herrera since taking charge at Old Trafford, and insists he will assess the squad following the pre-season tour of the United States before pursuing further deals.
A number of players have been linked with a move to Old Trafford since the Dutchman's appointment, with the 26-year-old Colombia international reportedly the subject of a £30 million-plus bid.
"I cannot talk about Cuadrado, because if I say something about him the price will rise," he told reporters.
Barcelona are also understood to be in the running for Cuadrado as a replacement for Dani Alves, though Fiorentina are hoping to hold out for close to £40m for their prized asset after securing 100 per cent of his rights early in the World Cup.
"We'll see the best situation, if there was an offer of €50m [£40m] he would be hard to give up, but at the moment there has been no official request," sporting director Daniele Prade told Corriere dello Sport recently.
