CRISTIANO RONALDO is one of the big names in danger of missing out on Euro 2012.

But he has vowed to secure Portugal's place in tonight's do-or-die clash in Denmark.

They need at least a point in Copenhagen against Sunderland's Nicklas Bendtner and Liverpool's Daniel Agger to clinch top spot in Group C — otherwise it will be play-off agony.

Ronaldo said: "We are going to Denmark to win.

"That is our thinking. We have the conditions to come out with victory. We know a draw is good enough but we want to win to go straight through."

GROUP A: Belgium, who boast a string of Premier League stars (Man City's Vincent Kompany, Everton's Marouane Fellaini, Chelsea's Romelu Lukaku and Fulham's Moussa Dembele) must match Turkey's result against Azerbaijan at group winners Germany or will miss out on a play-off berth.

GROUP B: Andrey Arshavin's Russia need a point at home to Andorra to qualify. Ireland require a draw at home to rivals Armenia to seal a play-off spot.

GROUP C: Italy have qualified. Serbia, led by Manchester United centre-back Nemanja Vidic, will edge Estonia out of the play-offs if they win in Slovenia.

GROUP D: Manchester City's Edin Dzeko's Bosnia go to France and a win will see them qualify. If the Balkans pull off a shock result, it will send Les Bleus to Les Play-offs.

GROUP E: Holland have qualified. Sweden are in play-offs. Beat Holland at home and they could go straight through as best runners-up.

GROUP F: Greece need a point in Georgia to qualify. Croatia can still go through as best runners-up with victory at home to Latvia.

GROUP G: England are through, Montenegro in play-offs.

GROUP H: Portugal need only a point in Copenhagen to beat Denmark to top spot. Norway face Cyprus with a hope of second place on goal difference ahead of Portugal should Denmark win.

GROUP I: Spain have qualified. Scotland will finish as runners-up if they beat the reigning World and Euro champs in Alicante. Otherwise the Czech Republic will seal a play-off spot by beating Lithuania.
