Pep Guardiola has hailed Fernandinho after the Brazilian filled in at centre-half for Manchester City's comfortable win over Shakhtar Donestk on Wednesday.
John Stones' injury in training meant Guardiola had one out-and-out centre-back to choose from in Ukraine.
Playing alongside Nicolas Otamendi, 34-year-old Fernandinho was impressive in the role, helping keep a clean sheet as City romped to a 3-0 victory.
Riyad Mahrez, Ilkay Gndoan and Gabriel Jesus were the scores for Guardiola's side.
Speaking after the game, the City manager heaped praise on his make-shift defender.
He said: "Fernandinho is a clever player and so intelligent, an incredible guy. He did well, it's the first game he played.
"He has a lot of experience and personality. What he says, the people follow him in the locker room."
He added: "He is a player who can play many positions and has a good personality - that's why he is so important for us. I didn't have doubts that he would [look so comfortable in the back four]."
