The Bianconeri travel to Glasgow to play the Bhoys in the last 16 of the Champions League tonight.
"We have followed Celtic's progress and we know that we must be careful," he told a Press conference.
"At home they will be very dangerous with their fans as a 12th man. We have the utmost respect for Celtic and realise the danger they pose.
"We studied them a lot and know they will be a physical side who get most of their goals from set pieces. Scott Brown is the heart and soul of the team and Gary Hooper is the kind of striker who could do very well in Italy.
"There are not many teams who could beat Barcelona at home and lose so narrowly away."
