Manchester City look the real deal this year.
After spending roughly £200 million in the summer to bolster their defence, Pep Guardiola has assembled a squad that have been steamrolling everything in their path.
Before the day began Manchester City sat top of the table, having picked up 16 points from a possible 18 in their opening six league games.
However, it is the manner in which they have accumulated these points which makes that tally even more impressive.
In those six games, they had scored 21 whilst conceding only two; with a 5-0 thrashing of Liverpool a stand out performance.
The two time Premier League champions therefore went into this evening's tie at Stamford Bridge with great confidence.
Despite Sergio Aguero being unavailable having sustained a broken rib in a car accident, City showed their class as they overcame Chelsea with a 1-0 scoreline.
Kevin De Bruyne was the man who made the difference; marking his return to the club that let him go with a stunning goal to earn three points for his side.
Manchester City were understandably ecstatic to get the victory over their title rivals, and the club could not resist taking a dig at Chelsea in their match report for letting De Bruyne go.

But Manchester City are right, why did Chelsea let De Bruyne leave?
Chelsea signed the Belgian in 2012 for a reported fee of £7 million, and immediately sent him on loan to German side, Werder Breman.
After an impressive year at the Bundesliga outfit, the then 22 year-old would find first team opportunities limited as he struggled to break through into Chelsea's squad.
After featuring just nine times in all competitions in the 2013/2014 season for Chelsea, the club let the midfielder return to the Bundesliga as VFL Wolfsburg signed him for just £18 million.
A few years later De Bruyne arrived at Manchester City, and a number of eye-catching performance has seen him grow into one of the best midfielders on the planet.
Despite making a £11 million profit on the former Genk man, Chelsea will almost definitely be ruing the decision to let him go for such a measly fee.
