The Spanish side were dominant in possession at the San Siro but were pegged back twice by rapid-fire AC Milan attacks with goals being scored by Sulley Muntary and Kevin Prince-Boateng.
Alves knows that the onus will be on his side to score more than two goals against the Serie A giants when they come visit the Nou Camp on Tuesday night for the second leg of the last-16 tie.
The Brazilian feels that Barca need to step back and take some bold moves in order to make it a goalfest and secure passage to the quarter-finals.
"We will do our utmost to try and win the game. If we don't take risks we won't win, though. We are not afraid of the task at hand," the full-back told Barca TV.
"We have shown to be a great team, but we have never completed a historic comeback. Perhaps the moment has come to do it.
Furthermore, he believes half the battle would take place in the minds of the players instead of on the football pitch.
“The problem is all mental. When you have negative things around you, it’s necessary to close yourself off, it spreads if you don’t," he continued.
"People need to see that you're going to fight to get to the next round. We need to have a connection."
Barcelona last missed out on the quarter-finals in 2007 when they were beaten on away goals by Liverpool.
