Dino Toppmoller hailed the way Bayern Munich's players overcame the absence of Julian Nagelsmann to clinch a 4-0 win over Benfica.
Bayern head coach Nagelsmann pulled out of the Champions League Group E game three hours beforehand with flu-like symptoms and handed the reins to assistant Toppmoller.
Two goals from Leroy Sane, one from Robert Lewandowski and an own goal from Benfica's Everton wrapped up a comfortable victory in Lisbon on Wednesday for the six-time winners.
It ensured Bayern have earned nine points from their first three games and are sitting pretty at the top of Group E, five points clear of second-placed Benfica with Barcelona further point behind.
Bayern have scored 12 goals and conceded none to give them their best start to a Champions League season and the joint-best overall in the competition.
"The boys were sensational, especially in the second half," Toppmoller told DAZN.
"Huge compliments to the team. It's not easy for the boys when the head coach pulls out at the last moment."
Benfica have never beaten Bayern in any of their 11 European meetings (drawn three, lost eight).
But despite the scoreline, Bayern did not have it all their own way and were indebted to two fine saves from goalkeeper Manuel Neuer when it was 0-0.
The Germany international managed a clean sheet on his 100th appearance in the Champions League as he became only the fourth player to reach a century of appearances for the club in the competition, and only the second goalkeeper after Oliver Kahn (103).
"It's gigantic, I never would have believed it," Neuer said of the milestone.
"If someone had said that to me at the start of my career, I never would have thought it was possible. It's a great time and we had a great crowd today.
"I think the second half was incredible. We gave very little away and had the control, but we couldn't really break through. When the first goal went in, things became easier for us. It was a great evening for us."
Bayern Munich’s nine unbeaten matches against Benfica in the European Cup/Champions League (won six, drawn three) is the most by a team against an opponent since the tournament began in 1955.
Sane opened the scoring with a 70th-minute free-kick then rounded it off six minutes from time and acknowledged Bayern could have won by an even greater margin.
"I think we played a really, really good game," Sane said.
"Even in the first half. In attack, we could have finished off our chances a little better. But I am really happy with the performance. We had just had to play our game and be patient; in the end it worked out."
