Barcelona manager, Luis Enrique has accepted the blame for the heavy defeat at Paris St-Germain, which leaves the Spanish giants in danger of failing to reach the Champions League quarter-finals.
No side in the history of the competition has come back to win from such a deficit.
“It was a disastrous night for us; we were clearly inferior,” Enrique said.
“I’m responsible for this.”
Barcelona are five-time European champions and last won the Champions League two years ago.
They have not failed to reach the last eight of the competition since 2007 and Enrique knows his side will have to be at their very best to have a chance of turning the tie around in the return leg at the Nou Camp on 8 March.
He added: “It’s extremely difficult for us now but we go back to our stadium and really we need a heroic performance.
“But why not dream?”
