Under Maresca, City have won each of their opening five Premier League fixtures so far this season as they sit perched at the top of the table above champions Arsenal and sixth-place Liverpool.
Liverpool come into this clash off the back of four wins across their last five matches in all competitions.
They are unbeaten in the league under Andoni Iraola, who will hope that Anfield will play a role in helping to beat City on Sunday afternoon.
Manchester City Verdict
The Premier League have confirmed that Manchester City have been found guilty of all charges related to breaching financial rules.

The ruling also states that Manchester City committed multiple breaches of its duties of co-operation and utmost good faith towards the Premier League, and that they were in 'significant breach' of both the Premier League and UEFA's spending limits.
