Manchester United will reportedly need to table a bid in excess of £45 million, in order to convince Juventus to part with their Chilean midfielder Arturo Vidal.
The 27-year-old has attracted the attention of several top clubs by impressing in the 2014 World Cup despite playing through injury.
However, the Red Devils have an upper hand over other suitors as the player is reportedly interested in moving to Old Trafford rather than Chelsea or Arsenal.
Still Vidal will cost United a considerable sum of money as Juventus, according to an ESPN report, will only listen to offers above £45 million.
And this will prove to be a bit of a problem for United, who have already spent around £60 million to get midfielder Ander Herrera (Athletic Bilbao) and left-back Luke Shaw (Southampton) this summer.
Although the United hierarchy are understood to be ready to splash out £150 million on transfers this summer, they might not want to break their club transfer record for Vidal.
Red Devils will be looking to bring in more players this summer and will also want to adhere to UEFA's Financial Fair Play (FFP) rule, in order to avoid punishment like rivals Manchester City.
Meanwhile, former United midfielder Paul Scholes feels his club should not have easily given up on the transfer of Bayern Munich's Toni Kroos.
Despite Kroos being one of United's main targets this summer, the club ended their pursuit for the German midfielder, after van Gaal reportedly asked them to look at other options.
And though they ended up buying Herrera from Bilbao, Scholes feels that the Spaniard does not come in the same class as Kroos.
"I love watching Toni Kroos. I think he's brilliant. I love the way he controls the ball and controls games. He can really play a pass and has superb vision," Schoes said on his blog for bookmaker Paddy Power.
"Kroos is capable of scoring goals too, from outside the box on either foot. I just wish Man United had signed him. Yes, it is good to see United bringing in new players, but they haven't signed anything like the quality of Kroos."
