Ronaldo scored twice in AC Milan's Serie A victory over Napoli on January 13 while Adriano also bagged a brace for Sao Paulo in a recent Campeonato Paulista match against Guaratingueta.

The forward duo have struggled for form and fitness in recent months and neither was included in Brazil's 22-man squad to face the Republic of Ireland on February 6, but Dunga is confident that both are on track to rediscover their best form.

He said: "I'm very happy they are back. They've been without games for a long time. Forwards love scoring goals.

"I hope they can keep up this progress. Everybody knows they have talent."
