Manchester City have again demonstrated why we should never underestimate them, with a fairly assured, 2-0 victory - away, against an in-form Everton side.
A settled defence is key
In previous years there have been question marks surrounding City's defence, not this year though, as Mangala continues to perform this season alongside a formidable captain in Vincent Kompany.
The match against Everton was no different, they made sure Romelu Lukaku had few chances and protected Joe Hart, who himself admitted that he didn't think he "had a great game", and yet City's impressive winning streak continues - which is undoubtedly the sign of a title-winning side.
Not to mention the signing of Nicolás Otamendi to further bolster their defensive options, providing much-needed experience at European level having featured in both Spain and Portugal.
Goal-scorers throughout the team
Not only do Manchester City have a solid back-four, they also have goal-scorers all over the pitch. When Sergio Agüero doesn't score, other players step up - like we saw against Everton. They have a whole range of world-class talents, not to mention Yaya Touré who has also rediscovered his form from two seasons ago, when he managed 20 goals from a central midfield role in just 35 appearances.
The Citizens have also scored the most goals so far in the league, with ten goals in total and you'd expect they could easily surpass the 100 goal mark for the second consecutive season.
But, is another striker needed?
With Stefan Jovetic and Edin Dzeko leaving Manchester for moves to Italy, there appears to be a gap in City's, otherwise packed, squad - with very few decent alternatives to their talisman Sergio Agüero.
Although, Agüero is obviously extremely talented; getting 26 goals in 33 apperances - there is still a question as to whether he can through the whole season without injury, if the worst was to happen, who do Manchester City have as an adequate replacement? Wilfried Bony? Raheem Sterling?
Firstly, Bony has not really got going for Manchester City yet; with just two goals in 10 appearances - eight appearances were from coming off the subsitutes' bench. Though he hasn't really been given an abundance of opportunities by Manuel Pellegrini, so there are still questions about his ability in a Sky Blue shirt.
Sterling on the other hand, has only played as a striker a handful of times for former manager Brendan Rodgers and in his first three games for Manchester City has looked nervous in-front of goal, could that pressure be too much for such a young player? Especially with that inflated price tag looming over him.
Their side is strong, very. But title rivals Chelsea have the advantage in the striker department with alternative options on the bench that can be equally deadly in-front of goal, although man-management is tough in itself. Will they dip into their funds to buy another striker? It's highly doubtful.
Major summer recruitments
Last year, many people questioned Manuel Pellegrini and his players, having lost out in the title race with six games still to play. This year though, with the addition of Raheem Sterling for £49 million, they look more of a threat - particularly through a more counter-attacking style, which they could not perform with David Silva out wide last year.
They are not just a counter-attacking side though, this style is one of many they can now perform effectively. This is a team without the additions of Fabian Delph, who has been out injured(hamstring), and the more recent signing Otamendi that cost them in excess of £30million pounds. Not to forget, the imminent arrival of Kevin de Bruyne for a reported fee between £50-55million in itself, City are just beginning to flex their financial muscles.
Surely that's more talent than you can fit into a squad and therefore makes them genuine UEFA Champions League contenders as well as obvious favourites for the Premier League title.
So much for sacking Pellegrini
Towards the back end of last season, there were plenty of people wondering as to whether Manuel Pellegrini would be sacked over the summer and potentially Pep Guardiola replacing the Chilean. But after signing a new contract extension just weeks before the new campaign began, it was a clear signal of intent by the club's owners who have shown their faith in Pellegrini - as the man to lead them forward in glory.
Their faith in him has been repaid as his side are now back to their best and most importantly have kept Yaya Touré at the club as he starts to perform well again.
It's still early days, though
Taking all of that into account, it's important not to get too carried away or complacent. After all, there are still another 34 league fixtures to play, many of which will be tough encounters against rival sides - José Mourinho is evidently feeling the pressure, but how will Chelsea respond to a poor start?
Even though Chelsea are obvious contenders as well, Arsenal, Manchester United and maybe even Liverpool could challenge for the title, however they look to have finished their spending for the summer and still seem too short of world-class players to properly challenge.
England's top flight is often unpredictable, which is part of the reason why it's considered the most competitive league in the world. City have started rather brightly, and if they stay consistent, there's no reason why they cannot win plenty of silverware this season.
