Chelsea boss Roberto di Matteo says Ramires' goal on halftime was crucial in beating Champions League opponents Barcelona on aggregate.

Di Matteo had no doubt what had been the main turning point in the game.

"Ramires's goal just before half-time gave us the lifeline and belief, that was a crucial moment.

"Barcelona are the best, they are amazing, but the way we defended we showed a lot of desire to go through, and we had a little bit of luck as well which you need."
