Shanghai Shenhua admit Carlos Tevez has failed to live up to expectations, but the club are yet to rule out extending the forward's deal.
Tevez, 33, has struggled since his lucrative move, scoring just four goals in 16 Chinese Super League (CSL) games.
"We decided to buy Tevez because the AFC Champions League qualifying phase was about to begin and at that time the new rules [to curb mega signings] did not come to light," he told Shanghai TV.
"Tevez was playing quite well in both Boca Juniors and Juventus. And since there was an arms race going on [in the CSL], our club need a player who has a reputation and universal appeal.
"Of course, in the end, he is not living up to those expectations. But he keeps working very hard to be in contention to play.
"As for whether or not to extend his contract next year, it has to be a mutual choice. His future hinges on the outcome of further negotiations between the two parties."
