Barca lost on aggregate to Chelsea on a stunning night at the Nou Camp.
Alves said: â€śIâ€™d like to thank all the CulĂ©s for your support and, at the same time, apologize for what happened. We tired but it wasnâ€™t meant to be.â€ť
Teammate Cesc Fabregas also said: â€śItâ€™s painful to be eliminated this way, seeing that we had a lot of chances to score.
"Itâ€™s a very hard blow."
