Thompson was a youngster with a big future, but when he went knocking on Keegan's door with his AGENT, KK was not a happy man.
We were running a Newcastle fanzine at that time and we spoke to Terry McDermott, who said: "It's amazing when you have kids, who haven't even broken into the first team, come with an agent demanding a new contract".
Keegan thought the kid was jumping the gun and he let him move on for a cut-price £200,000 transfer, and there was a touch of bad feeling at the time.
The Evening Chronicle says 34-year-old Thompson will take a coaching role looking after a certain age group at the United Academy as he gets the badges necessary to move further up the ladder.
I think we all know the appointment of Dennis Wise had (and still has) Keegan wondering what place the ex-Leed boss has within the walls of St James' Park.
This has many fans asking who is the "Daddy" at the club.
