The Old Trafford legend has been singing the praises of club record signing Juan Mata.
After a mediocre campaign at Old Trafford, David Moyes is expected to splash the cash on new players this summer.
The first addition in a bid to turn the tide was made in January, with Spain international Juan Mata signed for a club record fee from Premier League rivals Chelsea.
The ex-Valencia playmaker is yet to fully hit the heights that he displayed at Stamford Bridge, but his presence is a positive step to add creativity to an at-times predictable team.
Bobby Charlton has been full of praise for Mata and has admitted that he did not believe that United could sign the Spaniard from Chelsea.
"I like Juan Mata a lot," Sir Bobby told the club's official website.
"I must admit I admired him the very first time I saw him play on television, but I did not think we would have the opportunity to sign him. He is a fantastic player already but could go on to become a great one. I'm sure that's his aim.
"In the coming months and years, he will get the opportunity to score and make more goals because he is simply first class. You can already see how much he loves being here and he is a very nice man to go with it."
Mata has been forced to play on the flanks, with Wayne Rooney predominantly occupying the coveted number ten role.
Just where the Spaniard fits into the United attacking picture still is to be determined, but he undoubtedly is full of ability.
