La Liga leaders Barcelona have been in sensational goalscoring form this season and visit Real Sociedad on Sunday in La Liga high on confidence. The Catalans have netted 55 times in 16 matches across all competitions and have scored three times or more in each of their last seven outings. Basque side La Real have historically proven difficult for Barcelona to overcome in San Sebastian but Hansi Flick's side have swept aside any team to cross their path since September. Barcelona suffered their only league defeat six weeks ago at Osasuna and since then have thrashed Spanish and European champions Real Madrid 4-0, as well as beating Bayern Munich 4-1 in Europe.
