Custodio hopes Ronaldo will win Casillas duel
The two teams face off in Donetsk on Wednesday and Custodio, who hopes to play a part from the bench, said: "I hope Ronaldo comes off best in this duel - that's what I'm banking on."
Ronaldo has been in effervescent form with three goals in his last two games and Custodio said he could make a difference against anyone - even the Spanish.
"Ronaldo is one of the most complete players I know, both physically and technically and mentally. He is always motivated and will wear the shirt with great pride."
