Manchester United director Sir Bobby Charlton says things will be easy this season without European competitions.

The Red Devils had a poor previous campaign under the guidance of their former manager David Moyes as they finished seventh in the league table. This saw them miss out both the Champions League and Europa League this season.

Despite lack of European football, United have invested heavily in the transfer window as they have signed Ander Herrera, Luke Shaw, Marcos Rojo, Angel Di Maria, Daley Blind and Radamel Falcao.

The 20-time English champions look to bounce back after having appointed Louis van Gaal as Moyes' successor.

Robson has backed the Dutchman to shine as he believes it will be a great adventure for United this season under the former Barcelona and Bayern Munich manager.

"It seems strange that Manchester United aren't involved in European football for a season. It's crazy but maybe it can make things easier for us," Charlton explained.

"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."

"He [Van Gaal] has given me and most of us fans some good news. We won't struggle, definitely we won't struggle anymore," he added.

Charlton is the leading scorer for both United and England. He has scored 249 goals for the Red Devils and has 49 goals against his name for the Three Lions.

Wayne Rooney is eight short of matching his goal-scoring record for the national side, while 33 more goals would see him climb up the table as the club's all-time top scorer.

The United legend has backed the England international to surpass his goal-scoring record for both club and country.

"I've told him not to worry too much. He has my backing. I'll be quite happy when it comes. I told him: 'Think hard about it and maybe you'll have some good news. I've had good news from it all my life. I don't mind him taking it,'" the United legend said.

"It would a great achievement – and it would be a change for me. That's good. He's a good lad and I don't mind it at all," Charlton concluded.
