Arsenal have enjoyed a blistering start to the season, while Chelsea are putting together a run of good results. Many would have the London duo, who are currently first and second in the table, down as this season's Premier League title favourites.
But the bookmakers' favourites, and with good reason, are Manchester City.
Not only are they equipped with arguably the best squad in the league, there's an argument to suggest they also have the best coach.
Manuel Pellegrini hasn't taken long to discover what Premier League football is all about. Not that he would have been given much time to settle at the Etihad Stadium, but the Chilean is clearly a smart and smooth operator who knows how to get the best out of his players.
He's been ruthless when he's needed to be ruthless - as Joe Hart would testify - and early-season disappointments appear to have made him even more determined to ensure no opposing team is underestimated by his players.
Now they have their talismanic captain Vincent Kompany back, there might be no stopping Pellegrini's side, who have scored a remarkable 40 goals from their opening 14 matches.
They are currently two points behind second-placed Chelsea and six behind league-leaders Arsenal, so don't be too surprised to see City in pole position by the turn of the new year.
Of course, no team has ever won a league title in January, but City's impressive strength in depth suggests they may come on even stronger in the second half of the season - unlike Chelsea and, in particular, Arsenal.
For example, Stevan Jovetic - a class act who has barely featured for City this season because of injury - should be fit and raring to go. He could prove decisive when Sergio Aguero needs a rest, while Alvaro Negredo and Edin Dzeko are more than capable of causing damage, as we've already seen this season.
No Premier League team has four better strikers in their ranks - and this will inevitably help City during the latter stages of the campaign.
