Lionel Messi was sick before he took to the pitch for Barcelona's Liga game with Athletic Bilbao at the weekend, as the footage shows.
The Barcelona forward has had a problem with sickness and has regularly vomited during matches.
Manager Tata Martino was quoted in March, per BBC Sport, as saying:
"He has even gone to see specialists at certain times but their tests have proved inconclusive."
But those incidents, which sparked concern, were during matches rather than before games.
There has been no obvious effect on his form. In fact, Messi struck late with a free-kick to secure a 2-1 victory for Barca during the Bilbao game, keeping their hopes of defending their Liga title intact.
