Something hilarious has been spotted during Lionel Messi's disallowed goal vs Valencia

The big talking point from La Liga's weekend games was undoubtedly at the Mestalla.

Valencia welcomed league leaders Barcelona and let's just say it wasn't without controversy.

Lionel Messi - who now hasn't scored since October 21 - thought he had broken his mini-drought during the first-half, when Neto inexplicably spilled his tame shot over the line.

Every Barcelona and fan in the stadium could pretty much see that the ball was in but amazingly, the linesman didn't give the goal.

Valencia almost scored on the counter after the disastrous decision.

The game ended up finishing 1-1, with Messi teeing up Jordi Alba in the dying minutes to salvage a vital point.

However, footage of the disallowed goal points out something quite hilarious involving the Spanish left-back.

ALBA COULD HAVE BEEN AT THE DOUBLE

One eagle-eyed Twitter user spotted that Alba would have 100% scored the rebound, had he not decided to run away celebrating.

It's a case of hindsight but it should serve as a reminder that every player needs to play to the whistle.
