Milan visit Chievo on Tuesday while unbeaten Juventus, who snatched the lead from them at the weekend, are at home to third-placed Lazio on Wednesday in one of the closest Serie A title races for years.
Allegri, one of the less charismatic coaches in Serie A, is from being a chest-thumping motivator but on Monday clearly felt forced to make a rallying call after seeing his team fall a point behind Juve.
"There is too much negativity around us, nothing is lost," he told reporters, two days after a shock 2-1 defeat to Fiorentina at San Siro.
"It's over the top to say that Juventus are unbeatable and are going to finish off the championship.
"The road is still long. The criticism is raining down on us, but we still have great chances of winning the title.
"There are still seven games to go and if Juventus had a great chance when they were two points behind us, the same goes for us when we are one behind."
Antonio Conte's team have won their last four games without conceding a goal.
"We didn't expect them to come acropper after they had been ahead for so long... but one false step and it could all go down the drain."
