It was considered a highly controversial signing considering Benitez's past with Chelsea's fierce rivals Liverpool and certain nasty comments that he had made about Chelsea while managing Liverpool.
From criticizing the Chelsea board of handing him the title of 'interim manager' to regular 'Rafa Out' placards showing up at every Chelsea match, Benitez decided to quit the team at the end of the season.
In his short reign, he still managed to take Chelsea to the semi-finals of FA Cup and helped them win their first ever UEFA Europa League trophy in 2013.
