The Premier League enters Matchday 6 this weekend with a number of high-profile fixtures.
One such match will see Thomas Tuchel's high-flying Chelsea host defending champions Manchester City in Saturday's early kick-off.
The Blues are yet to lose a match this season, dropping just two points out of a possible 15.
City, on the other end, have dropped five points, losing and drawing once while winning three.
This will be the first time the two sides clash since the Champions League final in Porto when Kai Havertz's goal gave the London Blues the win.
Ahead of the match, we take a look at key battles that could decide the match.
Ruben Dias vs Romelu Lukaku
Ruben Dias has been outstanding for City since his arrival last summer and seems to have picked from where he left last season.
He will come up against Lukaku who has scored three Premier League goals so far following his summer switch from Inter Milan.
The Belgian is known for his energy, power, and ability to create space for his teammates, making the battle with the Portuguese international an exciting one.
N'Golo Kante vs Kevin de Bruyne
Arguably the best in the world in their respective positions, Kante and De Bruyne can single-handedly decide a match.
The two seem to have shaken off early injury struggles to help their teams in recent games, with Kante putting in a man-of-the-match second-half performance against Tottenham last weekend.
It will be interesting to once again see the fluidity and ability of the Belgian against the incredible work rate of the Frenchman.
Edouard Mendy vs Ederson
The two goalkeepers have been instrumental for their respective teams. Ederson won last season's golden glove, with Mendy coming second, and the battle seems on already.
Ederson has four so far and sits atop the pile alongside Liverpool's Alisson Becker, with the Senegal international with three having played a match less compared to the Brazilian.
Whatever happens, the two could be key in the outcome of a match that could have a long-term impact on the Premier League race.
