It has been a crazy Premier League season this year, with so many upsets happening throughout.
The season started off with potentially six title winning teams, which quickly narrowed down to four, then to three, and now surely to just two.
It seemed as if Jose Mourinho's fantastic home record would remain for yet another Premier League season after seeing off the most toughest of oppositions already at home. With bottom of the league Sunderland visiting on Saturday, Mourinho must have thought that his Chelsea side would easily come away with the win.
After a fantastic start from Chelsea, Samuel Eto'o grabbed the first goal from a corner. However, Sunderland almost instantly hit back from one of their own.
After that, Chelsea really struggled to create good chances and it was evident that Mourinho sensed danger as well after he sent on Demba Ba for Oscar with around 30 minutes to play. Sunderland ended up winning with a penalty, effectively ending Mourinho's title hopes.
However, Chelsea still have a Champions League to play for and at this stage of the competition, anything is possible. Chelsea are currently outside favourites for their tie with Atletico Madrid, but could pull through.
What doesn't help is that in the middle of this Champions League tie is the crucial clash with Liverpool.
With Chelsea almost certainly out of the title race, all they can do is help Manchester City or Liverpool gain an advantage.
They should field a side that leaves all of their key players rested for the important match with Atletico at Stamford Bridge.
If Chelsea do manage to win at Anfield - which at the moment seems highly unlikely - it opens up the real possibility of Manchester City coming back into the title race.
