The Argentine striker, along with attacking mates Sergio Aguero, Mario Balotelli and Edin Dzeko, continue to be linked with a summer departure from Eastlands but Mancini's comments on the club's official website indicate that things are rosy in the City camp at the moment.
"I think such speculation is normal, we have four top strikers and all the other teams in Europe would like strikers like them," he said.
"After January last year the problems with Carlos were finished.
"He came back to Manchester and his behaviour was good. He played a lot of games and scored important goals that helped us win the title.
"Now he has started the pre-season training very well."
