Paris Saint-Germain's new signing Marquinhos has said he hopes his move to the French champions will help earn him a place in Brazil’s World Cup squad.
Marquinhos, 19, became PSG’s third major signing of the summer when he completed a €35 million transfer from Roma last week.
The centre-back has not yet been able to train with his new team-mates but, in an interview with L’Equipe, he said he should be ready to return to action next week.
"I caught a virus when I returned to Europe," he told the paper. "I had stomach pains and infections in the mouth. I couldn’t eat too much, so I lost a few kilos.
"The medical staff at PSG carried out tests and they said that it was simply a virus that was in its final stages."
Le Parisien first detailed Marquinhos’ health problems earlier this week but he said that, contrary to what they reported, it was "nothing serious - definitely not hepatitis".
The former Corinthians defender was due to undergo a further check-up on Friday before resuming training on Monday.
Spanish champions Barcelona had also been interested in signing Marquinhos, but he said PSG’s ambition had impressed him.
"PSG are a team on the up," he said. "There are nothing but big players there. I made the choice with my family and my agent.
"And PSG are like a mini-Seleçao too – there are a lot of Brazilians. They’re going to help me to adapt."
Marquinhos said he had already met Alex and Lucas Moura and was hoping to form a strong central defensive partnership with Thiago Silva.
He has yet to play for Brazil, but said international recognition was a major motivation for the coming season, explaining: "I’m here to win titles and - if everything goes well - I hope to be able to be called up by the Seleçao. That’s my ultimate dream - to play in the World Cup in my homeland."
