La Liga leaders Barcelona lose 0-1 at Real Sociedad

La Liga leaders Barcelona fell to a 1-0 defeat at Real Sociedad on Sunday as they had a Robert Lewandowski goal controversially disallowed.

Sheraldo Becker’s 33rd-minute goal consigned the Catalan giants to their second league defeat of the season, leaving Hansi Flick’s side six points clear of second-placed Real Madrid, having played an extra match.

Lewandowski’s early disallowed strike led to furious debate over whether the Polish forward had been offside or not.

Barcelona were without teenage star Lamine Yamal after he suffered a blow to his ankle in the Champions League win at Red Star Belgrade midweek and badly missed his spark.

The Catalans failed to score in a match for the first time this season across all competitions as Real Sociedad, eighth, held firm.

Playmaker Dani Olmo started on the bench while defender Pau Cubarsi played in a mask after suffering a cut which needed stitches on his face in Serbia.

Barcelona have struggled at Real Sociedad in the past and were given another uncomfortable night in the Basque country.

Lewandowski thought he had fired Barcelona in front after 13 minutes when he reacted well to a blocked shot to fire home, but the goal was ruled out following a VAR review.

Referee Guillermo Cuadra Fernandez was told Lewandowski was offside, although the forward did not appear to be in front of Real Sociedad defender Nayef Aguerd.

The semi-automated offside technology used in La Liga indicated the front of Lewandowski’s boot was off, but Spanish media furiously debated whether the technology had misinterpreted Aguerd’s heel as part of the veteran striker’s boot.

With Barcelona’s strike chalked out, the hosts took control and tested visiting goalkeeper Inaki Pena several times.
