Liverpool boss Kenny Dalglish admits Craig Bellamy wasn't happy being subbed off during their FA Cup win over Oldham Athletic.
Bellamy was again outstanding on the night.
Dalglish quipped: "I don't know what he eats, but I think I need to get some of it! He was flying.
"He gets a wee bit frustrated coming off, but we've got to protect him as well. He'd love to play for 90 minutes and we'd love to have him for 90 minutes - but we'd rather have him for the next game, so we've just got to babysit him."
