Roma winger Amantino Mancini believes that Robinho will be the main threat for Real Madrid when both side clash in the Champions League on Wednesday. Mancini is confident of his team's chances of going through, but the Brazilian is wary of the danger his compatriot can cause. "Robinho is a beautiful athlete and will be a danger. But if we mark him well, we will win," said the Roma ace ahead of the crunch Santiago Bernabeu game. Robinho will carry the burden of delivering goals alongside captain Raul Gonzalez, as Dutch hitman Ruud Van Nistelrooy is a major doubt for the game. The Giallorossi have a 2-1 lead after their first leg victory in Rome, and Mancini has no doubts his team can oust the Spanish titans. "We are in good shape, both physically and psychologically, as we have demonstrated in the last few games, we are confident of this match's outcome," he added. "Roma are used to playing important ties. We have improved with respect to this in recent years - I think there will be no problems." Mancini scored the winning goal against the Madridistas at Olimpico a fortnight ago.
