Carlos Tevez's future at Manchester United has been thrown into fresh doubt after the striker's representative Kia Joorabchian declared he is ''studying other options''.
Tevez has been on loan at Old Trafford for nearly two years but with the deal expiring at the end of the season and United have failed to take up their option to sign the striker on a permanent basis.
"Carlos is in the market now that United have not made any move for him," Joorabchian told the Daily Star.
"We are now studying other options and interested parties. There is no option left with United any longer."
United missed the chance to seal a deal for Tevez in January, despite the Argentina international's repeated claims that he would be happy to stay in the Premier League and speculation has continued due to the fact he has only started 13 games this season.
Argentina boss Diego Maradona has urged Tevez to join Serie A leaders Inter Milan, who have been linked with a £30m bid (along with Real Madrid) in the summer, but Joorabchian's confirmation that the player's third-party owners are weighing up interest from other clubs suggests they will not be the only ones interested.
Tevez himself has said recently that he would have to wait until June to discover where he would be playing his football next season, claiming: "My mind is pointing me towards United and my plan is to stay here for several years more. I've already talked to the club and now we'll have to wait and see what happens in June.
"We talked but I've signed nothing yet. I want to stay. It would be difficult for me to quit one of the biggest clubs in the world."
Meanwhile, Corinthians have ruled out the possibility of signing Tevez.
The Argentina international had been the subject of rumours in South America suggesting he could return to the Sao Paulo club with his long-term future at United still unresolved.
However Corinthians football manager Mario Gobbi told Jovem Pam Tevez will not return to the club.
''He (Tevez) would like to play for Corinthians,'' said Gobbi. ''We have known this for a long time. Tevez identified with the club and is an idol for the fans.
''But it is only that, there is nothing else. We were surprised with the reports. Of course we would love to have him, but there is nothing in it at all.''
