Queens Park Rangers manager Harry Redknapp believes Louis van Gaal needs four or five signings in order to help Manchester United win the title in his first season in England.

The Red Devils had a disastrous campaign under David Moyes as they finished seventh in the league table and are out of the next season's Champions League. The Old Trafford club are now hoping to bounce back from their poor season.

As a part of re-building, United have already added Ander Herrera and Luke Shaw to the squad in the ongoing summer transfer window. The former Tottenham Hotspur boss hailed van Gaal's impressive track record, but says the Dutchman needs more signings to compete with Chelsea and Manchester City.

"Van Gaal's got a good track record but they need players," Redknapp told talkSPORT.

"He needs to bring four or five players in at least to get them back to where they were under Alex [Ferguson], where they were winning championships because they look well short of that at the moment.

"Certainly at this stage you wouldn't want to bet on them winning the league next year. I wouldn't see them winning it next year unless he suddenly pull three or four fantastic players out of the hat.

"I wouldn't see them being as strong as Chelsea or Man City," the QPR manager added.

Meanwhile, Arsenal added Alexis Sanchez to their strike force after the Chilean arrived at the Emirates from Barcelona. The Gunners completed the deal for Mathieu Debuchy on Thursday.

Redknapp believes the addition of Sanchez would see Arsenal also compete for the title next season.

"I think Arsenal have made a great signing [in Alexis Sanchez] so they could get a lot closer next year," the former Tottenham manager said.

"It's quite open. I would love to see Liverpool have another great season but they've lost an incredible player [in Luis Suarez], he's irreplaceable really," Redknapp concluded.
