Olympiacos goalkeeper Roberto was labelled "a Saint" following his heroics in Tuesday's 1-0 UEFA Champions League win over Benfica.
The former Benfica goalkeeper put in a spectacular performance against his old club as second-placed Olympiacos boosted their chances of progressing out of Group C.
Kostas Manolas headed home the only goal of the match in the 13th minute as he met Jose Holebas' out-swinging corner, but the hosts rarely threatened in attack after that as Benfica dominated.
Roberto was forced to make nine saves to retain the one-goal lead and coach Michel reserved special praise for the 27-year-old.
"It was a great night for us," said the former Real Madrid midfielder. "Our keeper (Roberto) was great. He was a Saint.
"I do not know what is higher than a Saint in the hierarchy. Perhaps the Pope?
"Football was fair to him. It was a rematch for him for the time he was at Benfica and things did not go well. He proved he is a worthwhile and good goalkeeper
"He has the passion and I am very happy for him, but all our players were great and I'm happy that we scored from a set-piece."
Michel added: "We're in a good position now and in good shape.
"We have seven points, but we must continue like this.
"We constantly defended. That was not our intention. We like to player higher, but I am happy because in four games we have seven points."
