Manchester City are in danger of another Champions League catastrophe after going into the break 2-1 down to CSKA Moscow at the Etihad Stadium.
Yaya Toure's free kick quickly cancelled out Seydou Doumbia's second-minute goal, but the CSKA Moscow striker scored again to put City behind at half time.
Doumbia, who scored off the bench in the 2-2 draw between these sides a fortnight ago, headed the Russians ahead when Toure allowed him to run free from a set piece.
City's Ivorian midfielder made amends on eight minutes by whipping an unstoppable free kick, earned by Stevan Jovetic's driving run, into the top corner from 22 yards.
The hosts had a brief period on top as Jesus Navas wasted a promising chance from inside the box, and Sergio Aguero weaved his way into a shooting position before having a low shot saved at the near post.
However, they were open at the back throughout the first half and Moscow made the most of one of several dangerous counter-attacks when Doumbia scored a third goal in two games against the Citizens.
Martin Demichelis poked the ball away from Musa Ahmed, only for Gael Clichy's hashed clearance to gift it back to CSKA, and Bibras Natkho slipped in Doumbia to finish emphatically into the bottom corner.
