"We found an agreement for an amicable early end to his contract, which was to have finished on June 30, 2013," the club said in a statement.

The 29 year-old Brazilian, who has battled drink problems and poor physical condition, arrived at Roma in the summer but has failed to hit the net once.

Adriano has won 48 caps for the Brazilian national team and took part in the 2006 World Cup in Germany.
