Chelsea skipper John Terry insists they won't get carried away after victory at Stoke City.
Terry, who scored their opener at the Britannia Stadium, believes the title is a three-horse race between themselves, Manchester City and Manchester United.
Asked if he feels Chelsea are on course to win only the club's third Premier League title in their history, the 34-year-old said: "No if you look at City they've come from nowhere and United are back in fold too. All it takes is a run of games from either side to overcome us.
"There's a long way to go and we've got West Ham next - who were a tough opponent for us last season [the sides drew 0-0 in the corresponding fixture at Stamford Bridge last term]. It's a cliche but we're taking it game by game."
