Liverpool boss Brendan Rodgers had no problem with Luis Suarez again being booked in defeat to Aston Villa.
Rodgers says he won't consider taking the passion out of Suarez's game.
"He is a passionate lad. I didn't think he deserved to be booked but he had a couple of incidents he was protesting about which went unpunished," the Northern Irishman said.
"I would never take that passion out of the game. That is what makes him the player he is.
"He's picked up some bookings this season but some of those were needless by the referees - like at Sunderland where he was booked for diving and it wasn't a dive."
