Manchester United manager Jose Mourinho has admitted that he is dissatisfied with the club's business in the transfer window so far.

As it stands, the Red Devils have added two new players in the form of defender Victor Lindelof from Benfica and Everton striker Romelu Lukaku.

Combined, the pair have cost over £100m, but if reports are to be believed, Inter Milan winger Ivan Perisic could also be on his way to Old Trafford.

"We always want more," Mourinho told ESPN. "We always feel there is room to improve, and I cannot say that I am happy with our transfer window.

"What I can also say is that it is a difficult transfer window and I don't blame anyone - it is just a reality of things. The market is going in such a direction that many players are difficult to get, not to say impossible. Every club is powerful and they don't want to sell or their demands are really high, so the market is difficult.

"The market ends on August 31, so there is plenty of time, but obviously, the objective for me as manager is always to have the players as soon as possible and try to coach them in the team and develop the team with them and Lukaku and Lindelof arrived to train in time for day one."

United will open their Premier League campaign on August 13 at home to West Ham United.
