Both sides fail to win their last game respectively.
Akhmat Grozny are beaten by CSKA Moscow after their 2 players are suspended, so that loss is justifiable. But their recent home performance is not stable.
As for PFC Sochi, they have got 2 wins and 1 draw in 3 away games so far this season. Their away quality cannot be underestimated.
So PFC Sochi should be supported in this match.
