Javier Zanetti is back in the frame for Argentina and will likely slot in at right back. The 37-year-old is a veteran of the game but is as good as any player in his position on his day, an evergreen footballer who refuses to surrender to age. The Inter legend already boasts stopping Lionel Messi last season in club football and tonight he will aim to pull all the stops on Cristiano Ronaldo.
Cristiano Ronaldo has established himself as one of the best players in the world and will float from one flank to the other. The 26-year-old is likely to start at left-midfield for Portugal, meaning that he will go head-to-head with Zanetti. Ronaldo has been ripping apart defences in La Liga but has often failed to gel for his national team. Tonight with Zanetti against him, it could be a tough 90 minutes for the former Manchester United winger, although he does have the option to drift to right-midfield and take on Argentina left-back Marcos Rojo instead.
Javier Mascherano will start in central defensive midfield for Argentina and will play the role of destroyer of Portugal's attacking moves. The Barcelona medio is regarded as one of the best in his position in the world, and although the 26-year-old hasn't looked at his best for the Spanish champions in club football this season, he will be keen to give his all for Argentina tonight.
Lionel Messi has developed massively as a withdrawn centre-forward for Barcelona and tonight he will start in the middle of a front-three for Argentina. There is no doubt that he needs special attention but with the 23-year-old's ability to drift inside from the wide, track back, pick up loose balls in the midfield, venture on darting runs from the middle of the pitch, it is almost impossible for any one player to man-mark the little wizard. However, tonight Bruno Alves will have to be physical and bully the FIFA Ballon d'Or winner.
Angel Di Maria v Fabio Coentrao
Fabio Coentrao is one of the best young wingbacks in Europe as he has demonstrated time and again that he has the quality and calibre to make it big. Tonight the 22-year-old will start at left back and will confront Angel Di Maria (and intermittently Ezequiel Lavezzi). Coentrao has proved himself to be supportive while going forward and is also steady at the back, and will hope to get the better of his old Benfica team-mate Di Maria tonight.
