UEFA Champions League: CSKA Moscow 1 Bayern Munich 3
Bayern Munich secured a record 10th UEFA Champions League win in a row by beating CSKA Moscow 3-1 in testing conditions at the Arena Khimki.
Arjen Robben's 10th goal of the season set the European champions on their way as the snow came down in the Russian capital and Mario Gotze doubled their lead early in the second half.
Keisuke Honda pulled a goal back from the penalty spot after spurning two golden opportunities after the break, but Thomas Muller responded with a spot-kick at the other end to ensure Bayern surpassed the record of nine Champions League victories in a row set by Barcelona in 2002-03.
Pep Guardiola's side will be confirmed as Group D winners if Manchester City fail to beat Viktoria Plzen later on Tuesday, but even if the Premier League side claim all three points then the German champions will only need a point against Manuel Pellegrini's side next month to ensure they claim top spot.
Victory also marks a club record sixth consecutive away win in Europe for Bayern, while CSKA are still in the hunt for a place in the UEFA Europa League ahead of their final game against Plzen.
Bayern striker Mario Mandzukic was ruled out with a calf problem, so Gotze started. CSKA were without in-form striker Seydou Doumbia due to injury and Ahmed Musa came in to replace him.
Guardiola warned his players to adapt quickly to the weather conditions and Bayern did just that to edge in front after 16 minutes.
Muller was the architect, racing away down the left and cutting the ball back into the path of the onrushing Robben, who made beat Igor Akinfeev with a clinical left-foot finish inside the near post.
Honda tried to be too clever when he attempted to round Manuel Neuer two minutes into the second half, but the Germany goalkeeper read his drag-back and smothered the ball.
Things went from bad to worse for the Japan international when a cross from the right fell nicely for him six yards out, but he fluffed his lines with the goal gaping.
And he was made to pay for those misses 11 minutes into the second half, when Gotze set off on a mazy run into the penalty and beat Akinfeev with a delightful left-foot finish.
CSKA were given a lifeline five minutes later, when Dante was harshly adjudged to have handled in the area and Honda this time kept his nerve to send Neuer the wrong way from the spot.
However, Bayern were awarded a spot-kick of their own after 65 minutes when Georgi Schennikov upended Robben and Muller restored their two-goal advantage. Zoran Tosic hit the crossbar nine minutes from time, but Bayern never looked in danger of surrendering their lead.
