Teenager Ngoo is already 6ft4 and has raised comparisons with the Spurs, England, and former Liverpool, centre-forward Peter Crouch.
The surprise was that he's gone to Liverpool after impressing in trails for Premiership champions Manchester United, helping them retain the Milk Cup in Northern Ireland during the summer, which was where he came to the of the Mersyside club, who also decided to take a look.
Southend will receive a small initial payment with the full £250,000 only being paid if Michael goes on to make his first team debut for Liverpool, and there may be more if he goes on to have a successful career with the club.
032Devil wrote at the time of the Irish tournament on redcafe.net: "He looked pretty impressive during the Milk Cup, good feet and good vision. He was a little raw and wasteful at times, but overall gave a good impression, none more so than in the final with a neatly taken goal and a great assist."
Head of Youth Ricky Duncan spoke to official site: "Obviously we would have liked to have kept the player but when an opportunity like this came along for him we couldn't stand in his way. Liverpool got in touch with us and offered him a trial. Then they made us an offer which we thought was a fair price. It's very early in his career but we believe he has the potential to go on and carve out a good career for himself at Liverpool. He leaves Southend with our best wishes and we're delighted that he has managed to move on to a club of Liverpool's stature."
