Lionel Messi posted a one-word message after seeing Argentina's Olympic opener against Morocco descend into absolute chaos.

Argentina's opening game of the Paris Olympics ended in a 2-1 defeat to Morocco after a chaotic game in Saint-Etienne. The Albiceleste equalised in the 16th minute of stoppage time but the goal saw fans storm onto the pitch and the match was suspended for over an hour.

The goal was subsequently ruled out by VAR for offside, with Morocco holding on to win 2-1 after play finally resumed.

Messi posted on social media after the final whistle. The Argentina legend wrote simple "insolito" which translates to "unbelievable" coupled with a flushed emoji.

There's no doubt that it's an ugly start to the Paris Olympic football tournament with fans also seen throwing objects onto the pitch. Argentina's national anthem was also booed by those in the stadium, with fans seemingly angry at footage showing Enzo Fernandez and his Argentina team-mates engaging in a racist chant during their Copa America celebrations.

Argentina manager Javier Mascherano was also furious after the final whistle. "The biggest circus I've ever seen in my life," he said.

Argentina will on to play Iraq on Saturday in Group B, while Morocco return to action on the same day against Ukraine.
