CSKA Moscow, bottom of Group E, host Manchester City in a game of life and death, as the Russians have not scored a single point in the current UEFA Champions League and the 'citizens' carry one, the product of a loss and a draw.
The Russians fell sharply in the first day in Rome (6-1), but got into trouble in the pre-almighty Bayern Munich (0-1) Pep Guardiola.
However, the Russian Army team has improved a lot in recent weeks, which has regained his best striker Ivorian Doumbia, and in the Russian league has climbed to second place.
The overwhelming victory of the weekend at the Kuban (6-0), ranked fourth, has allowed them to close the gap with Zenit, which only leads them as two points.
The Russian coach Leonid Slutsky, seems to have already found his starting XI, although against Bayern clearly decided counterattack and, ultimately, almost goes well.
Considering only worth against the English them victory is likely to opt out of the starting tandem of Nigerian striker Doumbia and screaming fast Musa, who was his country World Cup in Brazil.
Manchester City's Manuel Pellegrini also looking for his first victory. Winner of the Premier League in two of the past three seasons, has not yet signed a convincing performance in the Champions League in recent years, and this is one of the main tasks with which they came to Etihad in June 2013 Pellegrini a technician with extensive experience in international tournaments.
Despite having a strong team, the City will have to choke back again early European parties: they lost 1-0 away to Bayern Munich drew 1-1 against Roma after.
During his visit to Moscow, the 'citizens' trust in the moment of inspiration that crosses the Argentine Sergio Aguero to keep track of the top two spots in their group.
The "Kun" signed four goals for his team in the match against Tottenham last Saturday (4-1) in one of his more memorable with the shirt of City actions.
At that time two goals just before half Agüero served to trace the while the Russians had signed on the half hour.
Looking to match against CSKA, are doubtful for the City's French defender Eliakim Mangala with stomach problems, and Frenchman Samir Nasri, dragging pain in the adductors.
