UEFA Euro 2012 SF 1: TodayPortugal vs Spain 20:45 SS3GNIEWINO – Spain captain Iker Casillas can become the first player to notch up 100 victories in international football if his team beat Portugal in Wednesday’s Uefa Euro 2012 semifinal.To do so, on his 136th appearance for his country, the Real Madrid goalkeeper will have to thwart his club teammate and Portugal captain Cristiano Ronaldo, who has three goals at the tournament and has been on scintillating form.Eliminating the Portuguese, who have only beaten their Iberian neighbours once in seven competitive games, would give Spain a chance to become the first nation to win back-to-back continental titles with a World Cup in between.Casillas believes former World Player of the Year Ronaldo has still not quite reproduced the form that helped Real win La Liga for the first time in four years last season."His season at Madrid was incredible in terms of the way he played, the goals and the records,” the 31-year-old, known in Spain as "Saint Iker” thanks to his miraculous saves, was quoted as saying in Monday’s Marca sports daily."I don’t think that right now he is at his best level,” he added.A fired-up Ronaldo has been peppering opposition goals with shots in Portugal’s four Euro 2012 outings and Casillas said he will have to be wary of any deviation in the air due to the peculiar way Ronaldo strikes the ball.Spain’s last competitive meeting with the Portuguese came at the 2010 World Cup, when they won a close encounter 1-0 thanks to a second-half David Villa strike.Spain struggled to penetrate Portugal’s defence in that match in Cape Town but the introduction of towering striker Fernando Llorente early in the second half changed the game.Llorente, whose strength and height were too much for the Portuguese centre backs, could be an option on Wednesday if the game follows a similar pattern, defender Gerard Pique said.The winners of Wednesday’s game will meet Germany or Italy in Sunday’s final in Kiev.
