The Brazilian insisted that Milan had played well and were unlucky not to win the match but thinks three points against Celtic are more important now than a good performance.
Massimiliano Allegri does not believe defeat will cost him his job
Allegri denied failure to secure a win, and book their place in the knockout stages, would cost him his job.
"Not at all," he said. "Playing against Celtic will be very difficult.
"Maybe even a win for us won't be enough depending on what happens in the other match."
Responding to reports about players reporting late for training, he said: "What makes me angry is that false information gets out.
"For reports to say that five players were late for training is nonsense. I'd like to know where these stories come from."
When asked about his relationship with Mario Balotelli in particular, Allegri insisted that the former Manchester City striker, who missed a penalty against Genoa, was in his plans for the match in Glasgow.
"He will play tomorrow night," the coach added. "We've always got high expectations for Balotelli.
"I personally have a good relationship with him.
"For the last six months of last season after he arrived in January, he was very important for getting into the Champions League.
"He's going to be important for the rest of this season too."
