Chelsea host Manchester City on Saturday in a late night Premier League fixture as The Blues look to strengthen their position at the top of the table by beating the most realistic challengers for the title. On the other hand, this game will be one of the most important for in the remaining season Manchester City as the side managed by Manuel Pellegrini will have to grab the three points if they wish to retain the Premier League title.

The game is as exciting as they come and promises to be full of nail-biting action. This game can make or break the Premier League season and Saturday nighta s winning team might just see themselves crowned league champions at the end of the season.

As the two teams prepare to face the challenges on the pitch, we take a look at three key questions that will arise before kick-off.

Will Chelsea cope with Diego Costaa s absence?

Since his arrival in the summer transfer window, former Atletico Madrid striker Diego Costa has given the fans the pleasure of watching a proper goal-scoring striker, which Chelsea were lacking for a while. The Spaniard is competing with another former Atletico striker Sergio Aguero for the Premier League golden boot and is currently leading the race with 17 goals scored already. Costa has undoubtedly been a key figure in Chelseaa s success so far this season. However, as luck would have it, Diego Costa is set to miss one of the most important league games of the season as the striker has been suspended for three games for his antics in the game against Liverpool. In his absence, it will be interesting to see how Chelsea fares in their attacks and if they will be able to outscore Manchester City.

Can Sergio Aguero get his touch back?

Sergio Aguero has been having an excellent season; only to be marred by the problem he faces so often a injuries! However, Aguero has returned to full fitness but is yet to get his a mojoa back. The Argentine has scored 14 goals in the league so far and is just three behind the top-scorer Diego Costa. The game is a perfect opportunity for the striker to get his rhythm back and get Manchester City back on the fast lane. Aguero has a history of stealing the show, like he did earlier this season when with a hat-trick against Bayern Munich, and could do so yet again on Saturday against the league leaders. All the eyes of the Manchester City supporters will be waiting to watch Aguero work his magic, while Chelsea supporters will be praying that the Argentine has a bad day at the office.

Will Mourinho prevail at the Bridge yet again?

To say that Jose Mourinho has an impressive home record in the Premier League will be an understatement. The Special One has been vastly successful at home in the past and this season has been nothing different. Chelsea are yet to drop a single point at the Stamford Bridge as The Blues have accumulated 30 out of 30 points playing 10 matches at home. Stamford Bridge is a fortress where it will take something really very special to beat Jose Mourinho. Whether Manuel Pellegrini manages to do that on Saturday remains to be seen.
