The Portuguese coach has declared that his team will thrive on the pressure of a hostile atmosphere away from home and can only be content with winning the match.
He told UEFA.com: "Before the quarter-final first legs, I thought all eight teams were equal. However, my view has changed. Barcelona, Real Madrid, Juventus and Bayern Munchen are one step ahead of the others and I give each of these teams a 25% chance of winning the Champions League.
"If we lose 2-0 or 3-1 tomorrow, I won't return home happy. I want my team to win. After our first meeting I told my players that a team who won the first match 3-0 may lose the second by the same result. I said anything is possible and we must be very careful against Galatasaray.
"We have worked on the different defensive formations of Galatasaray. Although the fans can be intimidating, my players and I thrive in that kind of atmosphere."
