Ryan Giggs admits that Manchester United will find it tough against an in-form Chelsea side at Stamford Bridge on Sunday.
Chelsea may have dropped points in the UEFA Champions League, including a midweek defeat to Shakhtar Donetsk, but in the Premier League they have set the early pace, sitting four points ahead of Manchester United and Manchester City.
Despite having many new faces in the squad Chelsea have settled instantly, and Giggs is aware of the threat that Juan Mata, Eden Hazard and Oscar pose.
The veteran midfielder expects their opponents to be challenging for the title at the end of the season.
"Sometimes new players settle in straight away and that seems to be the case at Chelsea," said Giggs.
"They've got off to a great start this season, particularly in the league. We're going to have to play well if we're going to get a result.
"I don't know if they're the real deal but what they have got is that experience and the know-how of how to win a league.
"Obviously, having added to the squad like they have done, they're going to be right up there this season, no doubt."
He added: "Come the crunch, if they're there or thereabouts, they've got the experience like ourselves, like probably (Manchester) City now, to go all the way.
"I expect them to be up there at the end of the season.
"I think it is a different sort of Chelsea team. In past years they've had Didier Drogba's power and the runs through from midfield of Frank Lampard.
"We've always thought of Chelsea as a big, strong, powerful team.
"They've still got that but they've added the likes of Oscar and Eden Hazard, and Juan Mata is into his second season and coming along nicely.
"They've got clever players who can play in the pockets and make it difficult for teams."
