While they've earned just one point in Europe so far this fall and can not advance the Champions League knockout rounds, they still have a shot at making the Europa League - a shot that would be much improved by getting something out of this match.
The unpredictable contest took another twist as Rostov raised the roof with a brilliant third goal, courtesy of Noboa, who curled in a lovely free kick from 20 meters, after Thiago Alcantara had fouled Poloz on the edge of the box.
The Germany worldwide hobbled off after nearly an hour against the Russian side. That loss, which came in mid-September, sent Rostov's form spinning into mediocrity, earning only three wins since then in all competitions.
But Costa was largely to blame when Rostov pulled level a minute before the break - his backpass caught Boateng off guard, allowing Poloz to steal in and tee up Azmoun to round the Bayern centre-back for a tidy finish past Ulreich. In the European Cup draw in case of Rostov are somewhat worse, where after played 4 rounds in the asset team - crediting 1 point and 3 line in Group D, where the chance of reaching the playoffs does not remain, but the whole struggle will unfold for the 3- place and access to the LES.
Manuel Neuer has a tight calf and will stay in Bayern Munich for treatment.
The Portuguese swiftly changed his mind to give offside against Bayern, and Dzhanaev kept out Thiago Alcantara in the closing stages to ensure a first Champions League win for any Russian club over the Bavarian giants.
Of course, there's nothing major at stake for Bayern in this match.

The 21-year-old, who is nicknamed "The Iranian Messi", put in a fine performance as Rostov won their first ever Champions League game.
