Argentine internationals Sergio Aguero and Pablo Zabaleta have helped Tevez put last season's rift with boss Roberto Mancini, which cost him more than £10million in wages and fines, behind him and ended talk he could leave the Premier League champions.
Aguero, 24, said the trio drink a South American hot water infusion called 'mate'.
He said: "When they see me, Pablo or Carlitos drinking mate they think we are taking something illegal. It's funny. They don't believe we're drinking a kind of tea."
