Jim Cassell hopes his former protege Danny Sturridge grabs his chance at Liverpool with both hands.
The former City youth coaching guru told BBC Sport: "Hopefully Liverpool will get the best from Daniel as he has the potential to be a top-class international striker.
"Daniel was exceptional, even as a 13-year-old. He had great pace, fantastic feet and magnificent vision. I couldn't speak too highly of him when he was with us.
"He trained hard, was respectful and always immaculately turned out - I thought he was great. We knew he could go on and achieve great things."
