Barca’s last home defeat in La Liga was against Alaves in September 2016 (they have won 22 and drawn four since). The winning goal was Ibai Gomez’s first as an Alaves player. The Blaugrana are unbeaten in their last 27 games in La Liga (winning 24 of those), the best current streak of any team from the top five European leagues. Indeed, Barca could equal their longest unbeaten start to a league campaign in their history: 21 games under Pep Guardiola in 2009-10. Messi has provided at least one assist in each of his last five appearances in La Liga (five in total). Only two players have provided one in six games in a row this century: Andres Iniesta in 2013 and Dani Alves in 2011. Former Barca forward Munir El Haddadi has been directly involved in five goals in his last seven league games (three goals and two assists).
