Mazinho, a World Cup winner with Brazil, insists Thiago is prepared to stay with Barca and fight for a first team future.
"Sevilla was interested. Barca also told me directly that he had offers, but I never knew how long the contracts were, if they were four, five or one year. In no time I spoke about this issue. The press always talks a lot," said Mazinho.
"I knew their interest was the kid should stay here and continue his development."
