Adriano possessed all the tools required to become one of the best strikers in world football - and for a short time, he arguably was.
The Brazilian was at his peak around 2005, when he scored 28 goals in 42 appearances during the 2004-05 campaign for Inter Milan and was a regular starter for the Seleção.
Adriano, blessed with incredible power and a ferocious left foot, scored a total of 27 goals in 48 appearances for his national team between 2000-2010.

However, a series of personal problems blighted what should have been a spectacular career.
Adriano suffered from alcoholism, he put on weight, and found it extremely difficult to come to terms with the sudden passing of his father at the tragically young age of 44.
Adriano's career spiralled
His career spiralled.
Inter could no longer deal with the wayward forward, who returned to Brazil on a permanent basis in 2010.
Adriano flourished back in his home country with Flamengo, which earned him a move back to Europe with AS Roma, but the Italian club terminated his contracted just seven months into his Serie A adventure.
The South American then returned to Brazil, where he had forgettable spells with Corinthians, Atlético Paranaense and Flamengo again.
Earlier this year he signed a deal with Miami United of the National Premier Soccer League, but there was never any realistic chance of it working out.
Adriano gave up on football - and perhaps even himself - a long time ago.
Marca: Adriano is now living in a favela
Now comes the sad and unfortunate news, per Spanish newspaper Marca, that Adriano, who was once earning £80,000-a-week, is living in a Rio de Janeiro favela.
Photos have been published online showing Adriano getting his beard trimmed in one of the city’s most dangerous neighbourhoods, while another shows him holding up a gun.
This represents a new nadir for Adriano, whose career in football now appears to be as good as finished.
