Manchester City have received a huge boost after the Football Association decided to take no action against midfielder Yaya Toure for an apparent kick at Norwich's Ricky van Wolfswinkel.
The Ivory Coast star could have faced a three-match ban but the three-man panel of former elite referees which reviewed the incident did not unanimously believe it was an act of violent conduct.
Mourinho said: "If he (Toure) is not suspended, the message is clear: the players can do what they want if the referee doesn't see.
"If there's no suspension, the message is normally that, if the FA defends football, he'd have to be suspended.
"It's the same for everyone: if the referee doesn't see, I can do whatever. It doesn't matter about cameras or others seeing. I can do whatever I want."
A suspension for Toure would have come as a hammer blow to City's title hopes after Pellegrini's side dropped two points at Norwich on the back of losing to current Premier League leaders Chelsea.
Toure, arguably City's most influential player this season, will now be available for Wednesday's game against Sunderland, the FA Cup fifth-round match against Chelsea at the weekend, and the league fixture against Stoke.
Norwich boss Chris Hughton claimed Toure did kick his player, though said it was a "minimal incident".
The clash happened during the 0-0 draw at Carrow Road and appeared to be missed by match officials. Hughton said: "It did go unnoticed and there was no doubt there was a slight kick out.
"There was certainly something, but whether that was enough for a red card, then that is for the referee to decide on.
"It was a minimal incident in the game, and the bigger factor was it was a good team performance by us."
The news was also well received by Van Wolfswinkel himself.
The Dutchman tweeted: "Good to see Toure not getting suspended. Players like him belong on the pitch! What happens at Carrow Road stays at Carrow Road.
"Things happen on the pitch. But we all enjoy watching him play. So get on with it and enjoy the football. That's what it's all about."
