Andre Villas-Boas' side are currently 11 points clear of bitter rivals and defending champions Benfica, but their attentions turn to European matters as they travel to Russia to face CSKA Moscow in a last-16 first leg tie. The Colombia international has already helped himself to seven goals in European competition so far this term and Porto's hopes of reaching the last eight appear to be high as CSKA have yet to win against the Portuguese side - and have also yet to score a goal against them. But Falcao is desperate to again experience the feeling of being a league champion. He won the Argentinian Clausura during his time with River Plate but has yet to repeat the feat in Portugal. "I want to make history with Porto, to win the league as I did with River Plate in Argentina," said the 25-year-old. "Nothing can top that." While his focus may be on domestic matters, the forward expects a tough test at the Luzhniki Stadium and knows they need a repeat of their efforts against Sevilla in the previous round if Porto are to progress. "It was a difficult tie against Sevilla and we were relieved to advance but now we'll have to be at our best once again if we are to get past CSKA," he continued. CSKA's hopes of improving on their dismal record against Porto have not been helped by a series of injury concerns for coach Leonid Slutsky. Former Manchester United winger Zoran Tosic will definitely miss the opening leg after suffering ankle ligament damage in the Russian Cup win over Shinnik Yaroslavl, while Aleksandrs Cauna and Mark Gonzalez are also struggling in the wake of Monday's Russian Super Cup loss to Zenit St Petersburg. "This is a real catastrophe," said Slutsky. "Add to this the fact that Mark Gonzalez still hasn't been given a precise diagnosis, and you begin to believe in mysticism. "We need to not only alter our tactics, but to do it in the course of the most important of games."
