Liverpool defender Jamie Carragher goes into tonight's Champions League semi at Chelsea one booking away from suspension.

"It's not something that really worries me," he told "If it happens, it happens.

"It is all about not doing anything stupid because the worst thing would be if you picked up a needless yellow card for something daft like kicking the ball away or going through the back of someone.

"I was in a similar situation in 2005 when I picked up a couple of bookings in the group stages and had them hanging over me from that point onwards.

"So I know what it's all about and I'll be playing my normal game tonight. You can't do anything else."
