CSKA Moscow\'s title challenge stumbled today after they could only manage a 1-1 draw at home to city rivals Dinamo. A meeting between the second and third-placed teams in the Russian Premier League ended in stalemate, meaning the real winners were leaders Zenit St. Petersburg, whose lead over CSKA now sits at five points with a game in hand. CSKA took a third-minute lead when the league\'s top scorer Seydou Doumbia grabbed his 26th goal of the season, converting Keisuke Honda\'s pass with a neat finish past Dinamo goalkeeper Roman Berezovsky. But Igor Semshov grabbed the equaliser with 15 minutes to go, heading powerfully home from new signing Balazs Dzsudzsak\'s cross. The draw means Dinamo remain two points behind CSKA and seven adrift of Zenit.
