Fasten your seat belts people, in only the second round of Barclays Premier League fixtures, Manchester City await the champions of England in what is already being highlighted as a title deciding encounter.
Obviously, and this can't be overstated, it's only the second game of the season. Whilst pundits and supporters will look back on this as a starting block for either side, it can in no way be considered a league winning fixture.
One thing we can very much anticipate from this match up is the look of the players, and in particular, Yaya Toure and Nemanja Matic. The solid Serb's war in midfield against the Ivorian man mountain will almost definitely be a key sceptical. Here's why.

These two central midfield powerhouses have more in common than you think, to list but a few comparisons;
• They are both crucial to the midfield spine of their sides.
• Both are responsible for breaking up opposition play whilst starting attacks
• Both have been the key player in their respective sides title winning campaign in the past two years.
Most crucially, each of them have their own unique quality to bring to to the table on Sunday's 'battle of the billionaires' match up.
Nemanja Matic, 27, is mostly praised for his ability to sit in front of the back four and intricately break up opposition play. At the same time, he's capable of dribbling out the back and starting attacks of his own.
Yaya Toure, 32, however, is in no way famed for his effortless defensive contributions. Instead, the Ivorian is praised constantly for his driving runs from the midfield and being the figure head of Manchester City's midfield dominance and attacks.
For a quick summary, this battle will be intense and should decide the fate of this fixture, not just because of the importance and quality of the players involved, but also for their jobs against each other.
Matic's task at the Etihad this Sunday will be to try and render Toure's involvement as slight as possible. By being the shield between him and the Chelsea penalty area.
Who will win? It's simply way too close to call.
