Ex-Red insists the young forward will want to perform at his best against his former club, but admits the England international will not be able to pretend it is just another game
The England international left St James' Park in January to join the Reds for £35 million.
Now playing for the Merseyside club, Carroll has followed in the footsteps of Kennedy, who also left Newcastle in the hope of winning medals with Liverpool.
And ahead of the game against his former club, Kennedy says the forward will be professional about where his loyalties lie.
"It’s always a big occasion when you line up against your old club," he said, according to the Liverpool Echo.
"You can’t just pretend it’s the same as any other game.
"You want to impress and put in a performance which justifies you leaving that club in the first place. You want to prove that you’ve bettered yourself. I’m sure it will be the same with Andy."
He added: "Your only concern is doing your best and getting the best result possible for Liverpool Football Club. If anything in games like this you can try too hard because you’re desperate to do everything right.
"When that happens you can sometimes make mistakes. He has to try to relax and let his feet and head do the talking."
