Brazil defender Marquinhos has revealed how he was battling with diarrhoea and vomiting when given the "very difficult" task of marking Lionel Messi in their win over Argentina on Tuesday.
The centre-back was faced with the difficult keeping the Argentine sensation and attacking team-mates Sergio Aguero and Lautaro Martinez quiet in their Copa America semi-final.
The Selecao's tactics worked as they limited Argentina to just two shots on target in the game, while goals from Gabriel Jesus and Roberto Firmino fired Brazil through to the tournament decider against surprise package Peru.
