“I was happy with the goal, but I’m a little bit disappointed because we should win the game with three or four goals.”
“We are top of the group, we’re a good team, but it’s a long way for the final. These people, the club, they dream of winning the Champions League, but we have to take it step by step.”
Captain Giorgio Chiellini said the team would have to learn a lesson, with a tough Serie a game coming up against AC Milan on Sunday.
“We have to learn from this match if we want to get to (the final) Madrid in June,” said the defender.
“We knew Manchester have the qualities to make the difference and in the end we were not careful and good at bringing home a game that we deserved to win.”
Allegri added: “It leaves a bitter taste in the mouth, but we can’t win all the time.
“We need to find positives and that is that this defeat won’t be painful in the end.”
