There was a strange moment in the Sevilla v Barcelona game when Luis Suarez appeared to lose his head behind the pitchside billboards!
Inside the first 10 minutes of the game, Suarez missed a chance to open the scoring for Barca when he flashed a shot wide of the right-hand post after Jordi Alba's pull-back.
Upon viewing the replay of the situation - around 20 seconds into the clip - as the 31-year-old raises his hands to his head in disbelief, an overlaid graphic on the advertising hoardings appears to take the place of his head.
But look closely, because it's not the most obvious mistake until you really focus on it...
