Here is a look at three key battles you should watch out for as Manchester City play hosts to Arsenal on Sunday.

We are in for some exciting action as Arsenal travel to Manchester City on Sunday. Arsenala s most expensive player, Mesut zil is expected to start the game alongside the Chilean, Alexis Sanchez, who is in sensational form at the moment. On the other hand, all eyes will be on Sergio Aguero as the striker is expected to start his first game for City after returning from injury.

Here is a look at three key battles that will shape the gamea s destiny.

Mesut zil vs Fernandinho

Germany international Mesut zil will start a game for the Gunners after a long time. The German will be looking to show his skills in the big game, having missed a major part of the season through injury. The attacking midfielder plays his best football in the number 10 role and if he starts in that position, we can expect the former Real Madrid player to create some amazing chances for his forward. To contain the Germany international, defensive midfielder Fernandinho will have to step up his game. In the absence of Yaya Toure, Fernandinho has the task of containing Arsenal in the middle of the park. It will be interesting to see if the Brazilian can live up to the billing and stop zil from creating chances for the frontline.

Alexis Sanchez vs Pablo Zabaleta

Alexis Sanchez is in super hot form at the moment. The former Barcelona winger has been playing exciting football since his arrival in England and has already amassed 12 goals and 7 assists for the Gunners. Sanchez has proved to be the heart of Arsenala s attack as the Chilean is displaying some amazing football and also putting an impressive work-rate. Already a favourite amongst the Gunners faithful, Alexis will give the Manchester City defenders a hard time on Sunday. However, to contain the Chileana s threat, fellow South-American Pablo Zabaleta will have to be on his toes the entire game. Sanchez is quick, strong and clinical and it will be a very tough task for Argentina international, Zabaleta, to contain the winger.

Sergio Aguero vs David Ospina

Sergio Aguero is back to full fitness and is raring to go all guns blazing in attack. With 14 goals in the league, the forward is three goals behind top-scorer Diego Costa and on Sunday, Aguero will be more than motivated to close the gap. A fully fit Sergio Aguero is enough to give any defender in the world cold feet and the goalkeepers will have to be considerably alert to deny the Argentine of goals. David Ospina is expected to start the game ahead of the struggling Szczezny. The keeper signed in the summer transfer window will probably face his toughest challenge yet in the league as he faces Sergio Aguero at the Etihad on Sunday.
