Madrid, the record 13-time European champions, went down to a 3-2 home loss against Shakhtar Donetsk, showing how far Zinedine Zidane’s side are just now from the standards being set by Bayern.
Two months after scoring the winner in the final against Paris St Germain in Lisbon, Kingsley Coman put Bayern ahead against Atletico in Group A and later scored a stunning individual effort to wrap up the victory at an empty Allianz Arena.
In between Leon Goretzka and Corentin Tolisso were also on target for the German champions, with the latter’s strike a stunner from long-range.
“The winning goal in last season’s final is a good motivator, but it’s in the past now and we have fresh goals this season,” Coman told Sky Sports.
It was Bayern’s 12th consecutive Champions League win while the result for Atletico equalled their worst defeat under Diego Simeone.
Bayern next go to Russia to play Lokomotiv Moscow, who battled back to draw 2-2 at Red Bull Salzburg on Wednesday.
Eder put Lokomotiv ahead in Austria, only for Dominik Szoboszlai to crash in a brilliant equaliser.
A deflected Zlatko Junuzovic goal put the hosts in front, but Vitali Lisakovich headed in to earn the Russian side a point.
Disastrous night for Real
Real were 3-0 down at halftime against Shakhtar at the Alfredo di Stefano stadium and fell short with a second half fightback to get their European campaign off to a disastrous start.
A depleted Shakhtar were without 10 first-team players and nine members of staff due to coronavirus infections and had seven starters aged 21 or under.
Strikes from Tete and Manor Solomon, either side of a Raphael Varane own goal, gave the Ukrainian champions a three-goal halftime lead.
Luka Modric and Vinicius Junior pulled goals back and Fede Valverde thought he had grabbed an injury-time equaliser but his deflected shot was ruled out for an offside.
Missing the injured Sergio Ramos, Real have now won just one of their last seven Champions League home games. This was also a second defeat in five days as they prepare to go to Barcelona for the Clasico on Saturday.
“We lacked a bit of everything, but above all our confidence, which is the most important thing,” said Zidane.
