Carroll scored his first Liverpool goals in the 3-0 win over Man City and his performance won him the praise of his former manager.
Andy is excellent, I like the way he bullies defenders," said Shearer.
"He's a no-nonsense type of centre-forward - technically good, devastating in the air with a rocket left foot, and deceptively fast.
"What's more, Andy is mentally very strong, which is so important. During all his off-field problems up here, he never let anything affect his game."
