Roma president James Pallotta says Manchester United will have to pay a "huge" fee to sign Kevin Strootman.
Despite spending £153million on seven new players, Louis van Gaal still has money to strengthen his squad and defensive midfielder Strootman is one of the players on his shortlist.
The United manager knows Strootman well from his time as Holland coach and is interested in signing the 24-year-old once he makes a full recovery from the cruciate ligament injury that ruled him out of the World Cup.
Manager Rudi Garcia said Roma would not sell the player for less than €100m (£77m) last year and Pallotta's comments suggest the club are still holding out for that enormous fee.
"We want to put the best team on the pitch, that's the most important thing. But we're businessmen. If someone comes in with a stupid number for a player, you have to listen to it. You can't just say 'no, no matter what'," Pallotta said.
"My view is that I don't want Kevin to go, for example, but if someone offers a huge amount, you at least have to listen to them.
"You're running a team, so you have to look at what's best for everyone, not just one individual. That's the way the world works."
Roma signed Strootman from PSV Eindhoven for €19m in 2013.
