Real Sociedad boss Jagoba Arrasate is confident that his side can overturn their first-leg deficit when they welcome Barcelona in the Copa del Rey semi-finals on Wednesday.

Barca will enter the match as the favourites following a 3-0 win last week, but Arrasate insists that the Basque outfit have the capabilities to advance.

"I'm the first to believe and dream, although being aware that it will be very complicated, but now we have a chance. To realise that chance, the first thing to do is believe. The team also looks convinced to me and hopefully we'll experience a magical night at Anoeta," he told reporters.

"We need to score two goals and to do that, we have to attack from the very first minute, but we also have to make sure they don't score an away goal, so we'll have to look for a balance. When we have to defend, we'll have to do it well and aggressively."

Sociedad enter the match on the back of a goalless draw with Levante in La Liga.
