Ronaldo is struggling with a knee strain.
"We hope that Cristiano is in good enough shape to play and to help the team," Nani told reporters at a press conference. "He is going well and he is relaxed about it, things are going the right way. If, for some reason, Ronaldo is not there, whoever is there playing has to be confident in their ability to get the job done.
"The World Cup is a one-of-a-kind challenge," the Reds winger continued, when pressed on his own ambitions. "I want to be fully fit, and in top form alongside my team-mates. I could not be there last time [in 2010], but happily, I am here now."
