Match-winner Joshua Kimmich admitted holders Bayern Munich were made to work for their 2-1 win at Lokomotiv Moscow on Tuesday which secured a record 13th straight Champions League victory for the German giants.
After Leon Goretzka gave Bayern an early lead in Russia, Lokomotiv deservedly equalised when midfielder Anton Miranchuk finished off a counter-attack on 70 minutes.
Lokomotiv squandered a golden chance earlier on when forward Fyodor Smolov headed straight at Bayern goalkeeper Manuel Neuer from point-blank range.
Bayern striker Robert Lewandowski shot wide before the European champions took the lead with a goal created by French internationals Corentin Tolisso and Benjamin Pavard.
Bayern head coach Hansi Flick made a double substitution at the start of the second half with German winger Serge Gnabry making his first appearance since recovering from coronavirus and Javi Martinez introduced.
