There had been reports that the Argentina international could be offloaded in the summer following a tumultuous stay. The 29-year-old escaped to South America without permission after he refused to warm up during a Champions League fixture last season.
Despite the forward's controversial stint at the club, Marwood has insisted that Tevez is in manager Roberto Mancini's plans.
"I think he is in a good place at the moment," the Daily Star quotes Marwood as saying. "Roberto Mancini has talked about extending Tevez's contract and these conversations will continue in the summer.
"We have had no offers and Carlos is happy at the club. Discussions will take place at the end of the season in terms of his future at City."
Tevez has one year left on his current deal in the North-West.
