Stoke boss Tony Pulis cannot understand why David Luiz's challenge on Jon Walters cannot be examined retrospectively. Pulis was furious Blues defender Luiz received only a yellow card from referee Michael Oliver for the tackle in the closing stages of Saturday's 1-0 defeat at Stamford Bridge.
Pulis said: "The worst thing is that Luiz's challenge is a very, very poor one but, because the referee's seen it and booked him, he's not going to miss a game.
"It's a like a policeman watching a bank robber rob a bank and, because he's seen it, the police are going to let him off.
"Whereas, if he didn't see him, they're gonna arrest him.
"It's absolutely crazy - ridiculous.
"But I don't make the rules. I'm just a football manager."
