Chelsea boss Jose Mourinho has criticised the FA's decision to let Yaya Toure off the hook after the Ivorian escaped a ban for seemingly lashing out at Norwich striker Ricky van Wolfswinkel on Saturday.
Toure appeared to kick the Dutchman while he was on the floor during Manchester City's 0-0 draw with the Canaries at Carrow Road.
However the FA decided not to retrospectively punish the midfielder, a somewhat controversial decision after Cardiff's Craig Bellamy was charged for lashing out in a similar fashion during his side's defeat against Swansea.
While Wolfswinkel later tweeted that he was happy to see the Manchester City man avoid punishment, Mourinho says a decision not to charge Toure wouldn't reflect well on the game.
Speaking before the FA's decision, the Chelsea manager was asked how he would feel if Toure was let off the hook.
"I don't understand why you say 'if'?" he replied.
"If he's not suspended, the message is clear: the players can do what they want if the referee doesn't see. The message is normally that, if the FA defends football, he'd have to be suspended.
"Of course, I would be disappointed if he is not punished. If he is not, it has to be the same for everyone: if the referee doesn't see, a player can do whatever he wants.
"It doesn't matter about cameras or others seeing, I can do whatever I want. If they make the rule that action can be taken if a referee has missed something, they have to apply that rule."
The decision means that Toure is free to line up for Manchester City against Chelsea in the FA Cup fifth round on Saturday.
Chelsea and Manchester City have been battling both on and off the pitch in recent weeks.
The Blues got one over on their rivals with a 1-0 victory at the Etihad Stadium last week, while Mourinho and Manchester City boss Manuel Pellegrini have been trading barbed comments in recent weeks.
