MUNICH — Five-time champion Bayern Munich gave Russian debutant Rostov a rude welcome to the Champions League on Tuesday, winning 5-0 in a record 13th consecutive win at home in the competition.

Goals from Poland striker Robert Lewandowski, Thomas Mueller on his 27th birthday, two from rising star Joshua Kimmich and another from Juan Bernat gave Carlo Ancelotti’s team a perfect start in Group D and maintained the side’s winning start to the season.

Last season’s beaten finalist Atletico Madrid won 1-0 at PSV Eindhoven in the other group game.

“The first goal is to win the group. We started well. The next game at Atletico will be tough,” said Ancelotti, who has made the best start as a Bayern coach for 18 years.

Bayern has now scored 20 goals and conceded none in five wins from five games across all competitions.

Manchester United had the previous record of 12 consecutive home wins in the Champions League from 2006 to 2008.

Rostov had never before played in the group stage of a UEFA competition and the Russian runner-up was counting on its defense, the meanest in the Russian league last season, to keep Bayern’s attack at bay.

The home side dominated possession but needed a penalty to break the deadlock in the 28th minute, coolly scored by Lewandowski after he had been wrestled to the ground by Rostov captain Aleksandr Gatskan.

Bayern defender Mats Hummels needed attention after taking a kick in the face from Miha Mevlja, who was trying to clear in the penalty area. Despite the dangerous challenge, no penalty was given.

Mueller put the home side in a comfortable position before the break when he converted David Alaba’s whipped-in cross from a central position.

Rostov’s first real chance — when Cesar Navas forced Manuel Neuer into action after a corner — was followed by Bayern’s third goal in the 53rd, when Kimmich continued his recent good form by converting Douglas Costa’s cross from close range.

The 21-year-old Kimmich had scored his first Bundesliga goal on Friday and his first goal for Germany against Norway the Sunday before that.

Kimmich grabbed his second Champions League goal seven minutes after his first, with a glancing header inside the far post from Bernat’s sharp cross.

Neuer denied Aleksandr Erokhin a late consolation before Franck Ribery crossed for Bernat to round off the scoring in the last minute.
