Sir Bobby Charlton believes it's only a matter of time before Manchester United hit the ground running and return to winning ways under the guidance of highly coveted Dutch coach Louis van Gaal.

Despite enjoying a promising pre-season, United have failed to win any of their first four competitive matches of the season, including an embarassing 4-0 defeat against MK Dons in the Capital One Cup. 

The next test comes against Queens Park Rangers at Old Trafford this Sunday, and with new summer signings Marcos Rojo, Daley Blind, Angel Di Maria and Radamel Falcao all expected to make their home debuts, Charlton is excited about what lays on the horizon.

He said: "We’ve started with some new players, we’ve not been playing well but we will play well. I think that it’s going to be a great adventure of how we pull ourselves back round and get back to the way it used to be.

It’s just such a strange environment the way that it’s all happened, that Manchester United is out of the news, but it won’t be for very long."

Charlton admitted that being without European football for the first time since 1982 is hard to countenance, but also suggested that this may help as van Gaal looks to rebuild: “It seems strange that Manchester United is not involved in European football for a season.

“It’s crazy but maybe it can make things easier for us. We have started with some new players, we have not been playing well but we will play well."

On van Gaal, United's former number 9 is adamant the Dutchman will bring success to Old Trafford. He said: “He has given me and most of us fans some good news and it is good news.

“We won’t struggle, definitely, we won’t struggle anymore. We are set fair."
