Manchester United boss Jose Mourinho is reportedly 'frustrated' with his club's lack of urgency in this summer's transfer market.
Just one new signing has arrived at Old Trafford this summer, with Swedish centre-back Victor Lindelof making the move from Benfica.
It is understood that Mourinho also wants Real Madrid's Alvaro Morata, Inter Milan's Ivan Perisic and Chelsea's Nemanja Matic, but all three of those deals are still up in the air at the start of July.
According to The Sun, Mourinho wanted all four new signings to travel with the squad on their pre-season tour of the United States next week, and the lack of urgency from the club's vice-chairman Ed Woodward has left the Portuguese dejected.
It has been claimed that Man United are close to a deal for Matic, but moves for Morata and Perisic are not imminent as Real Madrid and Inter Milan fight to keep hold of the duo.
Man United will face Los Angeles Galaxy, Real Salt Lake, Manchester City, Real Madrid and Barcelona during their pre-season tour of the United States.
