Jamie Redknapp is of the belief that Manchester United will need to make some major changes to the squad this summer.

Former Liverpool midfielder Redknapp has doubts over a number of key players as the Red Devils prepare for what is set to be an extremely busy summer transfer period at Old Trafford.

"I think it has been a decent season for United, nothing more, nothing less," Redknapp told Sky Sports 'Football Special'.

"There are a lot more questions than answers; (Angel) Di Maria, (Robin) Van Persie, obviously (Radamel) Falcao is going to go, the goalkeeper (David De Gea), it's going to be a transitional period again for United next season.

"I don't think they are close to winning the title next year. I don't think they will go close.

"When you look at the quality players, some of them, like Di Maria, have not achieved what they should have done this year. Do you carry on with him or do maybe sell him? That's the difficulty they have.

"(Louis) van Gaal is the right manager for Manchester United but I still feel they are a long way off."
