Cristiano Ronaldo said Monday he was ready to answer the call for Portugal in Saturday's crucial 2010 FIFA World Cup South Africa™ qualifier at home to Hungary after missing Real Madrid's first Liga loss of the season at Sevilla with an ankle injury.

"I have recovered well. We'll see how things go but I think I'll be fine come Saturday," Ronaldo said on arriving at Obidos, where the squad are preparing for a match which will go some way to deciding if they can snatch a playoff place after a poor showing in Group One.

If we don't believe we can do it (qualify) then it's not worth showing up for the national side.

The Portuguese currently stand third - five points behind leaders Denmark and two adrift of Sweden, while Hungary are level on points with Carlos Queiroz's side, rendering a win imperative ahead of an expected three easy points in their final game against Malta.

The Swedes have a tough encounter away to the Danes on Saturday. "These are decisive matches which we must win," observed Ronaldo, who said that team spirit was "fantastic" despite his country's irregular showing to date. "If we don't believe we can do it (qualify) then it's not worth showing up for the national side."

Ronaldo insisted that the Hungarians were there for the taking. "They are a physically strong team, but if Portugal play normally they will - and must - win."
