Aston Villa goalkeeper Emi Martinez clashed with Brazilian police before Argentina's World Cup qualifying win at the Maracana.

Fans started fighting during the national anthems, which led to Brazilian police entering the away section and attacking Argentina fans.

Police were seen punching supporters some fans were seen with bloodied faces as they were taken from the stadium on a stretcher.

Martinez was spotted climbing the hoarding to stop a police officer wielding a baton before being pulled away by team-mates.

Eventually, Argentina won 1-0 with a 63rd-minute winner from defender Nicolas Otamendi.
