Manchester City are through to the FA Cup fifth round after a superb 2-0 win away at Cardiff on Sunday.
De Bruyne’s opener was a clever free-kick that fooled the Cardiff defence, and Sterling powered in a header to make it two.
Bernardo Silva also had a goal ruled out.
The win came at a cost, though, with Leroy Sane going off at half time after a heavy challenge from Joe Bennett.
“Sane will be out,” Pep Guardiola said afterwards. “I don’t know how long for, I am not a doctor. Tomorrow we will see.
"They [officials] have to protect the players. Not my players. All players.
"They [refs] are there to protect the players. When there is fault, there is fault, and when it is dangerous, it is dangerous.
“I don’t understand the goal [Bernardo] that we didn’t get, but that is okay. We can accept that.
“But they have to protect the players. They have to do their job."
