Oliveira was left stunned by the performance of Real No1 Iker Casillas, admitting: "There is no room for sympathy in football, we couldn't get past Casillas and Real Madrid with their quality has scored the two goals needed to win this game.
"Casillas was incredible. He is the best goalkeeper in the world."
The on-loan AC Milan striker added: "I think two teams are battling for the Liga, Real Madrid and Barcelona, but after playing against them, no doubt, the big favorite today is Madrid."
