Real Sociedad striker Portu struck as they saw victory against AZ Alkmaar in San Sebastian.

It wasn't always easy on the night for La Real who, at times, still looked haunted by what had happened against the Italians.

Both goalkeepers were called into action in a frantic opening 40 seconds, but the LaLiga Santander side grew more dominant as the game wore on.

A couple of chances fell their way before the visitors' first, though the hosts got back on top after half time.

The breakthrough finally came for Portu as a shot fell his way, allowing him to tap in the game's only goal from close range.
