Luis Enrique has insisted that his Barcelona side has the "capabilities" to win the Spanish Super Cup at the expense of Athletic Bilbao.
The champions go into tomorrow's second leg at Camp Nou up against a 4-0 deficit from Friday evening's first meeting at the San Mames.
However, despite the fact that the odds are stacked against his players, Enrique has refused to give up hope of a turnaround.
"The comeback is a challenge that is within the team's capabilities. It would be arrogant to say we will do it, but we will try for sure," he told reporters.
"The stimulus is to do something that no-one has done before, that's how difficult it is. We will try to give Barca fans a great night."
The Catalans scored four or more goals on 18 occasions last season.
