Lightning struck twice on Arsenal
After Chalov gave CSKA Moscow the lead in the first half, Nababkin doubled the Russians' lead to move one goal short of the comeback.
Petr Cech gifted Chalov the opener when he failed to parry clear, and the Arsenal man between the sticks put one on a plate for Nababkin for the second.
In an almost carbon copy of the first, a long range effort was flapped at by Cech only for Nababkin to follow it up and score.
Arsenal, who cruised into the game with a three goal advantage, were suddenly not as comfortable in the tie.
