FC Barcelona produced their best 45 minutes football of the season as they came back from a goal down to beat La Liga leaders Real Sociedad 2-1 in their latest encounter.

Real Sociedad had lost their previous 24 league visits to the Camp Nou, but may have thought their luck was about to change when Willian Jose opened the scoring as Portu crossed back into the Barca penalty area following a corner in the 27th minute on Wednesday evening, reports Xinhua news agency.
