Brazilian midfielder Denilson has admitted that he is unsure of whether he will return to Arsenal when his loan deal with Sao Paulo ends in the summer of 2013.

The 24-year-old is in his second successive season on loan at the Brazilian club and there has been little to suggest that Arsenal will want to bring him back to the club when his latest deal expires.

Denilson made more than 150 appearances for Arsenal during a five-year spell in north London but fell out of favour in the 2010-11 season and was allowed to join his former club Sao Paulo on an initial season-long loan.

However, Gunners boss Arsene Wenger was prepared to allow him to leave once again in the summer and Denilson now admits that he is uncertain where he will be playing his club football next season.

"I will see out my contract (with Sao Paulo) which ends on June 30, 2013. But I don't know what will happen after that," Denilson told Globo Esporte.

"I hope my situation is solved quickly so I have nothing to worry about and so I can remain calm for the rest of the season."

Denilson has enjoyed some success since returning to South America as he helped Sao Paulo win the Copa Sudamericana earlier this month.

He will also be competing in the Copa Libertadores as Sao Paulo take on Bolivian side Bolivar over two legs, as they look to advance to the latter stages of the competition.

With plenty of competition for a place back at Arsenal, with the likes of Mikel Arteta, Aaron Ramsey, Abou Diaby and Jack Wilshere, it seems likely that Wenger will look to sell the midfielder on a permanent deal once the transfer window opens next summer.
