The former Prime Minister of Italy emphasised that he will not be telling coach Massimiliano Allegri how to set up the team, and is aware of the task at hand.
"It will be very difficult to beat Barcelona," the former Italian Prime Minister told RTL 102.5.
"I still haven't found the time to talk to boss Allegri, but I won't tell him what side to pick - I've never done that. I know the role of the president and that of the coach - I respect those - but a president has the right to give advice to his coach.
"On this occasion my suggestion would be that Messi is man-marked."
