Seedorf believes the clash will reveal the true potential of the Rossoneri.
“It is a big game, we have met each other quite some times in the last six or seven years so I am very much looking forward to that,” Seedorf told Sky Sports News.
“I feel it is a very fundamental match for Milan to understand the real potential of the squad so I am looking forward to it.”
“Manchester have a great squad, they have made some changes but as we see they are still competing perfectly in the English league,” he added.
“I feel it is going to be a match of truth for Milan in Europe to really understand our potential and I said this last week we have to keep on dreaming.
“It was perhaps more impossible to do what we did in 2007 than this year.”
