Do or Die for Portugal - - Portugal Will Take on Hungary With Full Strenth on Saturday, As Cristiano Ronaldo Delared Fit

Cristiano Ronaldo has declared himself fit to star in Portugal's critical World Cup qualifier against Hungary on Saturday night.

Portugal were approaching a game that could end their hopes of reaching the finals in South Africa with a fitness worry hanging over their captain and inspiration after he suffered an ankle injury when playing for Real Madrid.

A strong challenge from Marseille defender Souleymane Diawara ensured that Ronaldo missed Saturday's La Liga defeat at the hands of Sevilla but the £80 million world-record signing expects to be in peak shape when kick-off looms in Lisbon.

"I am almost at 100%, and with more treatments today [Friday] and tomorrow I will be in full condition to play," Ronaldo said.

Chelsea defender Jose Boswinga has also been passed fit by Portugal manager Carlos Queiroz after missing his side's 2-0 victory over Liverpool in the Premier League last month and may start the crucial encounter.

Portugal - level on points with Saturday's opponents, two behind Sweden and five behind Denmark - must realistically beat Hungary to maintain their challenge for a place in the finals as a draw will eliminate them if Sweden beat Denmark in Copenhagen in Group One.

Even if Portugal do win against Hungary then they may still need Denmark to win as Sweden have a home game against Albania on the final matchday and should win. Meanwhile, Portugal are home to Malta.
