Carlos Tevez has filed a written request for a transfer from Manchester City according to British media reports on Saturday.
The British Press Association says it confirmed the move, even though Tevez and the club have made no official announcement.
Since his controversial move from Manchester United 18 months ago, Tevez has been hugely influential and a fan favourite for City.
He's scored 39 goals in 60 appearances, ensuring a possible departure would leave a big hole in the team ranks.
But Tevez misses his two daughters who are in Argentina, and his relationship with manager Roberto Mancini has deteriorated despite being named captain at the start of the season.
He didn't attend the players' Christmas party, and missed the 3-1 win over West Ham on Saturday because of suspension.
