The former Inter Milan star is preparing for Flamengo's Libertadores Cup campaign but has been linked with moves to Roma and Inter's city rivals AC Milan.

Adriano has rediscovered his goalscoring touch and has scored 25 goals since his return to Brazil in 2009, including six in his last six appearances this year.

And his agent Gilmar Rinaldi believes the time has come for the 28-year-old to move back to Europe.

"Adriano is ready to return to Europe, with a squad which is a bit Brazilian," Rinaldi told Centrosuonosport.

"That could be Roma, Real Madrid, or Barcelona. Squads which work with Brazilians.

"He is ready to return, I'll go around and together we will evaluate the situation."

However, Rinaldi believes that nothing will happen until after this summer's World Cup.

He added: "It's difficult for anything to happen before because his contract is until the end of May.

"He'll play in the World Cup and then decide."

Adriano ended his contract with Inter by mutual consent in April after a torrid eight years at the San Siro, later revealing he had to leave the Serie A giants because of alcohol problems.

The Brazilian had a troubled time in Italy and his career was often called into question by off-the-field reports.

In September 2007, he was sent home to Brazil by Inter as he was unhappy, and he went on to join Sao Paulo on loan for six months before heading back to Italy.

Reports at the time suggested Adriano was once again turning up to training drunk and the Brazil international admitted that was why the Nerazzurri eventually gave up on him.
