The pair were team-mates when Mellor spent time on loan at West Ham last season and although the young striker didn't have the best of times at Upton Park, Michael could see what he was capable of.
Mellor scored twice in 16 appearances for the Hammers before returning to Anfield where opportunities continued to be sparse until last month, when injuries to strikers Djibril Cisse and Milan Baros handed Mellor his chance.
He responded with a double against Middlesbrough in the last round of the Carling Cup and, finally, the best moment of his Liverpool career when he lashed home that injury time winner against Arsenal.
Michael said: "It was hard for him at West Ham but I always thought Mells was a good player, a great finisher and you always knew what you were going to get from him.
"He works hard, he's a team player but what stood out for me was his finishing.
"He has always banged them in for the reserves at Liverpool and people have waited to see whether or not he could make the step up.
"He's come in for one-off games and it's always hard to prove yourself in those circumstances but he's in there at the moment and scoring a winner like that against Arsenal will only help him.
"All credit to him, he's leading the line for Liverpool, scored against Arsenal and things are going well for him.
"He's a good lad and it's nice to see him doing well again."
Michael Carrick wasn't surprised to see Neil Mellor lash home his stunning winner for Liverpool against Arsenal on Sunday.
