An early season favorite to win the league surfaced on Sunday when the last two champions of the English Premier League took the field. Defending league champions Chelsea looked like a shell of their former selves when they traveled to the Etihad Stadium in Manchester to take on City.

City started strong from the opening whistle. After only 15 seconds, David Silva sent a sublime ball that freed up Sergio Aguero in front of goal. Aguero, last season’s leading goal scorer, couldn’t finish the chance.

The missed opportunity only made City hungrier. The home team was always the most likely side to score. But Chelsea’s goalkeeper Asmir Begovic, newly signed from Stoke City, kept the defending champions in it with a few impressive saves.

But City eventually broke down the Chelsea back line in the 31st minute thanks to a typical Aguero goal that left defenders scratching their heads and sitting on the pitch. After a pretty give and go with YaYa Toure, Aguero finished with a low curler that beat the keeper.

After seeing an end to a chippy first half, City had to hold strong on defense after Chelsea came out of the locker room strong. Chelsea playmaker Edin Hazard had a chance to equalize in the 70th minute but his shot went straight to keeper Joe Hart. Chelsea never got closer than that.

The floodgates opened for City after Captain Vincent Kompany headed one in the net from a corner in the 79th. The center back doesn’t see many chances and finished with a whopping zero goals last season. After scoring two in two games, he is on pace for 38.

The match was decided, but Fernandinho made Chelsea’s awful week even worse after sending a cracking shot past Begovic to make it an embarrassing 3-0 loss to Jose Mourinhno’s squad.

After a draw at home to start the season, Chelsea’s manager suspended two members of his medical staff after he believed they hurt the team’s chances to get a win. Mourinho, never far from controversy, faced a massive backlash from the British media.

The members of the staff, one of them a female, ran onto the field to help a player they believed needed to be treated. That caused the player to be sidelined for a small amount of time after Chelsea had already been knocked down to 10 men after a red card.

Chelsea captain John Terry was subbed out to open the second half. This marks the first time he has been subbed under Mourinho, his manager for five seasons. That is sure to stir the pot even more in London.

Psychologically, Manchester City must have an edge over the rest of the Premier League. The 2013-14 champions have started the season with two straight 3-0 wins. They now sit five points above Chelsea and three above Arsenal. Crosstown rivals Manchester United also started with two consecutive wins, but they look far less impressive.
