Manchester United manager Louis van Gaal has hinted that he may not make any more signings during the summer transfer window.

The Red Devils have made two summer signings thus far with Ander Herrera joining from Athletic Bilbao and Southampton's Luke Shaw. United have been linked to various players all through the summer window, with Arturo Vidal reportedly being close to a move to Old Trafford.

However, van Gaal, who is currently in the USA as a part of United's pre-season tour, has admitted that he is no hurry to bring in new signings. The manager says he is willing to give the current players a fair chance to stake their claim for a place in the team.

The Old Trafford club have had a successful pre-season and are yet to be beaten in the three matches that they have played, and van Gaal has said that he doesn't think they need new players, since the team that he has at his disposal currently are winning all their games.

"I want to give the current players an honest chance. We are winning everything, maybe we don't need other players," van Gaal said, as quoted by the Daily Mail.

"Anyway, the transfer window still has a month left."

The former Barcelona and Bayern Munich manager has also revealed that he will be sticking to his 3-5-2 formation for the upcoming campaign, as he doesn't see his philosophy working with four defenders on the pitch. However, he did admit that there will be times when he might have to change his system.

"I can't see my philosophy working with four defenders," the Dutchman explained.

"It will be five. Maybe there will be a time when I have to play with four. We will see. Now all the sessions are arranged for the five defenders system," the Red Devils boss added.
