It was a hotly anticipated class featuring two teams who want the Barclays Premier League crown come May. It was a fierce game and city started better, with Petr Cech lucky not to be caught out with less than a minute on the clock.
In terms of chances for City, David Silva must hang his head in shame after missing two sitters, whilst Yaya Toure saw a volley flash past the post. Cech made two phenomenal saves from a Silva free-kick and a late Stevan Jovetic effort.
Chelsea had the best of the chances though with Eden Hazard proving very difficult to handle throughout.
Samuel Eto'o struck the woodwork after Hazard flashed a low cross across goal, whilst Joe Hart will be glad for his post after Nemanja Matic's 30-yard pile driver hammered off the upright. Gary Cahill hit the post for the third time after his header caused problems for City.
In all honesty, Chelsea had the best chances and if City had grabbed a late equaliser, Mourinho and his boys in blue would have been kicking themselves for not finishing their rivals off.
In the following the Chelsea players will be evaluated:
Cech - 7
Cech had a nervy first minute when a mix up between him and Cahill caused a bit of a panic at the back. He grew more composed after that though and had to scramble across goal to push David Silva's free-kick over the bar. The big goalkeeper was called into action in the last minute when he had to save a powerful shot from outside the box.
Ivanovic - 8
Branislav Ivanovic proved one again that he is a big game player. His passion on the field and his determination make him a valuable asset against teams like Manchester City. His fantastic winning strike and the celebration, which was aimed at an advertisement Hart stars in, made the day for Chelsea fans all over the world.
Cahill - 8
Cahill has become a real rock at the back and his partnership with John Terry has become so effective that Roy Hodgson and the FA must be regretting the fact that Terry will not be on a flight to Rio come June. Cahill put in a number of great blocks and was not affected by the occasion in the slightest. To his credit, he managed to keep Alvaro Negredo quiet - not something easily done.
Terry - 7
John Terry has made an amazing come back this season after being cast off to the side under Rafa Benitez. With the return of The Special One came the return of Terry and the return of the tightest defence in the league. Terry was Captain, Leader, Legend once again on Chelsea's biggest night of the 2013/14 season.
Azpilicueta - 7
Cesar Azpilicueta has been a revelation at left back and faced a tough task when coming up against the duo of Jesus Navas and Pablo Zabaleta. He dealt with the problem in a mature and controlling way and the threat was abolished. Navas is a very traditional winger who went on the outside and tried to beat Azpilicueta with pace on his weaker side. Azpilicueta stood strong and defied the challenge.
Luiz - 7
When Mourinho arrived at Stamford Bridge he said that, in his eyes, Luiz is a defender and not a midfielder. Since then he has changed his mind and yesterday saw a very assured performance in the centre of the park. Luiz dominated his opposition and very rarely left Silva alone - therefore nullifying City's creative spark.
Matic - 8
On his full debut, Matic showed just why the Chelsea management team swallowed their pride and brought him back to Kings Road for such a large amount of money. He marked Toure out of the game which is something no midfielder has managed since the big Ivorian's arrival in England. He matched Yaya Toure for power, pace and skill. His best moment came when he smashed the post with a thunderbolt from 30 yards.
Ramires - 6
Ramires was deployed on the right wing for his pace and persistence going forward but also to cover Kolarov, who i renowned for his forward runs and pin point deliveries. He was effective but showed the weaknesses to his game as well. He needs to improve his finishing and his final pass. A perfect example is when Chelsea broke with four on one and Ramires should have opened the scoring. Nevertheless, Ramires was a vital cog in the machine that Mourinho built to beat the opposition on the day.
Willian - 7
Willian has really come into his own since his arrival in SW6. His work rate is amazing and he has a creative side to boot. Like Ramires, he must work on his final ball and his set pieces leave plenty to be desired. Willian seemed like a luxury addition to the side but now it is obvious why Chelsea spent so much money on him.
Hazard - 9
Hazard has stepped it up a level this season and was the creative hub of the Chelsea team against City. His unexpected strength allows him to stand up to bullish defenders such as Zabaleta and he made the Argentinian, who is one of the best full-backs in the league, look very ordinary. Mourinho's tactics were built on Hazard creating a link between the defensive six and the attacking four. The Belgian's importance cannot be stressed enough and Chelsea fans should enjoy every single moment he is on that pitch - MAN OF THE MATCH
Eto'o - 6
Eto'o seems more back to his old self with every passing game and that is a credit to the player and the Chelsea fitness coaches. He works very hard and he oozes confidence and experience. His performance was not worthy of fireworks but his hassling and closing down from the front is a vital part of the way Mourinho wants to play. The Cameroonian's best moment came when he hit the woodwork from a low Hazard cross in the first half.
Oscar - Came on in the 83rd minute for Eto'o but could not influence the game hugely at a stage where Chelsea were seeing it out with their backs to the wall.
Mikel - The typical Mourinho substitute when Chelsea are one goal ahead and need to shut up shop. Mikel provided steal for the final minutes whilst wasting some precious stoppage time. Came on for Willian who became the slowest man to walk the face of this earth when he saw his number go up.
Ba - Demba Ba has had a tough time of it this season and the final seconds of a game cannot really be counted as 'getting minutes', however he did have an impact as he belted a loose ball high into the sky and killed off City's chanced of a come back.
