9 Things Chelsea Fans Need To Know About Diego Costa

7. He Knocked Chelsea Out Of The Champions League Last Season

Chelsea fans will need no introduction to Diego Costa. They will know enough about him before he has even taken to the Stamford Bridge turf having watched on with dismay as the Brazilian ended their Champions League dream last season. The Blues had been paired against Atletico Madrid in the semi-finals of Europe's premier competition last term and, with the first leg ending in a goalless stalemate in Spain, entertained Madrid in the second leg with home advantage. It was not enough however as a Costa-infused Atletico beat the Blues 3-1, with Adrian cancelling out Fernando Torres's opener before Costa put his side ahead from the penalty spot. Arda Turan added a third to kill off Chelsea's wavering hopes of reaching a third Champions League final in seven seasons while Costa and co. proceeded to the final, where they lost to bitter derby rivals Real Madrid.
