Brendan Rodgers believes Celtic's Europa League win over RB Leipzig is his side's best victory at home during his two-year reign as manager.
Leipzig sit fourth in the German Bundesliga but were beaten 2-1 by the Scottish champions.
"It was a fantastic victory and one that I'm very proud of," said Rodgers.
"I think tonight was a proper win for us against a top-class side sitting high in their domestic league and everybody knows Leipzig's quality."
After hammering Rosenborg 5-2 in Norway, RB Salzburg lead Group B by six points from Leipzig and Celtic, so it looks likely the German and Scottish clubs will compete for second spot.
Because Rodgers' side did not match Leipzig's 2-0 win over Celtic in Germany, Ralf Rangnick's team remain second as a result of their head-to-head record.
But Rodgers said: "The most important thing was to win and win well and I think we did that."
When asked if it was his best and most satisfying win in Europe at home as Celtic manager, he agreed considering "the level of the opponent" and quality of performance.
"The players were absolutely brilliant," he said. "And then the supporters were absolutely magnificent.
"It is always a very emotional game here at Celtic Park, but that synergy between both got us the result and it was a fantastic three points for us."
'This was a great step forward'
Rodgers pointed out to his players before kick-off that "if it has gone against them a bit, sometimes the game has got away from us".
So although Jean-Kevin Augustin cancelled out Kieran Tierney's early goal with 12 minutes remaining, Celtic got the winner through Odsonne Edouard within 14 seconds.
"Tonight was a great step forward for these players because, at 1-1, when Leipzig didn't deserve to be level in the game, they responded straight away and had that belief to play forward and get that fantastic winning goal," Rodgers said.
"This was a pressure game that we had to win, but you see the positivity of the team.
"We showed no fear, had plenty of aggression and brought our identity to the game."
Rodgers said it continued the recent improvement in performances from his side and was particularly pleased at the way they countered Leipzig's tactics.
"They were playing a system that can be very hard to press against - that midfield diamond," he added.
"The players knew they had to work hard defensively, they were aggressive, they fought for every ball and then they showed their quality when they had it."
