Portugal coach Paulo Bento is sweating over the fitness of three key players - Cristiano Ronaldo, defender Pepe and midfielder Raul Meireles - for Friday\'s Brazil 2014 qualifier against Russia in Moscow. Fenerbahce\'s Meireles became the latest doubt after suffering an injury in training on Thursday. We\'re going out there to win and to leave here with a total of nine points. Bento ahead of the trip to Portugal \"Raul injured himself today, while Ronaldo [shoulder strain] and Pepe [thigh strain] had their first training of the week, and we\'ll take a decision [on their availability to play] tomorrow,\" said Bento. Real Madrid duo Ronaldo and Pepe picked up their injuries in last Sunday\'s El Clasico, which finished in a 2-2 draw with Barcelona. Looking ahead to the Group F tie Bento said: \"Russia have the same objective as us so there\'s no favourite, but we\'re going out there to win and to leave here with a total of nine points.\" Both countries boast a maximum six points from their opening two matches, five points ahead of their four group rivals.
