Barcelona maintained their unbeaten La Liga record this season as they cruised to victory over Athletic Bilbao.

The hosts scored after only eight minutes when Paco Alcacer, who replaced the suspended Luis Suarez, steered in Jordi Alba's pull-back.

Lionel Messi made it 2-0 with a low 20-yard strike following good work by team-mate Ousmane Dembele.

Philippe Coutinho also hit the crossbar twice and Paulinho hit the post for La Liga's leaders.

Barcelona are 11 points clear at the top of the table, with second-placed Atletico Madrid playing at Villarreal later on Sunday (17:30 GMT).

No team has gone an entire 38-game La Liga campaign without defeat; Barcelona have nine league games remaining, having won 23 and drawn six of 29 matches played so far.

The record for an unbeaten run from the start of a La Liga season is 32 games, set by Real Sociedad in 1979-80.
