Former Barcelona and Milan forward Maxi Lopez believes the Liga side can beat the Rossoneri if they play at their best.
The Blaugrana host Massimiliano Allegri's men at Camp Nou this evening, trailing 2-0 from the first leg of their last 16 Champions League tie.
But the Sampdoria striker is confident that Jordi Roura's team can win, but only if they play to their maximum.
“If Barcelona play at their best, they can go through,” he told COPE. “It is always hard for opponents at Camp Nou.
“I had to play their last year for Milan, and it was almost impossible.
“But this year's Milan are organised and tactically very strong. I'm sure they will try to counter-attack.”
