"Barcelona" head coach Luis Enrique refused to raise his hands after a crushing defeat in the Spanish Super Cup match in Bilbao.
The "La Liga" champions suffered a painful 0:4 defeat and will have to work a miracle on Monday to win another trophy.
"I had to make a lot of changes in the lineup because we only had three days to recover from the UEFA Super Cup match. I take responsibility for the loss," Enrique said.
"Our schedule was hectic, as we recently returned from Georgia, but now is not the time to look for excuses. It's just the nature of the competition calendar.
The strategist praised the opponents, but promised a rematch at the "Nou Camp" stadium.
"We didn't have an easy match against the 'Athletic' team. I congratulate them, but on Monday, the atmosphere will be completely different.
Is a comeback at home possible? Today we only played the first part of the match. If there is a team that can turn things around, it's "Barca."
