Manager Sir Alex Ferguson has dramatically lowered the age of the side with the regular inclusion of David de Gea, Phil Jones, Chris Smalling, Tom Cleverley and Danny Welbeck, while the likes of Ryan Giggs, Michael Carrick and Dimitar Berbatov have been left on the bench.
But United, who have often been slow starters in the past, have immediately hit top form in their opening fixtures as they aim for a record-breaking 20th top-flight title.
Charlton told BBC Sport: "It's a very unusual start for Manchester United but it's fantastic.

Charlton, a World Cup winner with England in 1966, said of Rooney: "He is a marvellous player. You can tell he is very happy at the moment and he will score a lot more goals this season and beyond."
