Bayern Munich coach Jupp Heynckes still found something to quibble about at the end of his 1000th Bundesliga game as coach, despite his side's 6-1 win over Werder Bremen.
The record Bundesliga champions tore Bremen apart, leaving them with an almost unassailable 18-point lead at the top of the table as they close in on a 22nd title.
Yet Heynckes is seeking perfection and he did not quite see that in his side's latest victory.
"What annoys us a little is that we conceded a goal," he said.
"We had not counted on that. During the interval, we said to ourselves that it was important to keep a clean sheet, but we can cope with that."
With such dominance in the Bundesliga, and a comfortable 3-1 advantage over Arsenal from the first leg of their Champions League last-16 tie, Bayern can now focus all of their attentions on a third competition.
They face defending Bundesliga champions and cup holders Borussia Dortmund in the quarter-finals of the DFB-Pokal at the Allianz Arena on Wednesday when their treble aspirations will be put to the test in a knockout match.
"That's going to be a really huge game," Heynckes told Sky television. "Borussia Dortmund are champions and cup holders, while we are the dominant force this season.
"It's certainly going to be tight because we are two top teams, but I'm confident that a win is possible because we are in top form."
