Barcelona must wait a little longer to be confirmed as Spanish champs after drawing 2-2 with Athletic Bilbao.

The visitors were out of sorts for an hour at San Mames and deservedly trailed to Markel Susaeta's first-half goal, but the introduction of substitute Lionel Messi swung the match as he scored one and teed up another for Alexis Sanchez.

And it looked like the points would go back to Barcelona until Ander Herrera popped up to snatch a point for Bilbao.

Although Barca remain the runaway leaders, this result means they cannot seal the title this weekend.
