"We pressed high up the pitch and we took advantage on the counter," the Italian told reporters. "We played really well and all the players worked hard so congratulations to them.
"Cristiano's absence motivated the players. It made them work even harder. They all did well. You have to play as a team to beat Barcelona and we did that.
"Barcelona tried but we knew how to play against them. We needed to be compact and we were. We will take strength from this for the other two competitions."
Ronaldo was full of praise for his teammates following the final whistle at the Mestalla.
