Ronaldo backed to be pick of Real Madrid & Barcelona stars in Portugal v Spain clash

The Real Madrid star looks set to be vital if the Seleccao are to stand any chance of beating La Roja in the European Championship last-four clash

Cristiano Ronaldo will be the decisive representative of the El Clasico sides when Portugal take on Spain in Wednesday's Euro 2012 semi-final, according to readers.

The 27-year-old has been criticised for his performances at international level in recent years, but has put in some eye-catching displays this summer, captaining the Seleccao to the last four of the competition.

After scoring the only goal of the game against Czech Republic in the quarter-final, the Real Madrid star received just over 54 per cent of the vote from readers, who believe he will have the biggest impact of any Barcelona or Real Madrid player.

Ronaldo has been in scintillating form since leaving Manchester United for the Santiago Bernabeu in 2009, scoring just under 150 goals in his three seasons in Spain.

Despite such consistent efforts for his club, the former Sporting CP winger has often struggled to transfer his excellence to the international stage. But his fantastic brace against Netherlands, which secured qualification from Group B at the expense of the Dutch, silenced some of his critics.

Many believe that it is now down to Ronaldo to defeat La Roja and carry Paulo Bento's side to their second final in eight years.

He beat off competition from Madrid's Iker Casillas, Alvaro Arbeloa, Sergio Ramos and Xabi Alonso, as well as Barcelona's Gerard Pique, Andres Iniesta, Xavi and Sergio Busquets. Or maybe 'false nine' Cesc Fabregas will prove more vital.
