Redknapp is surely a shoe-in, seriously no idea about the rest...
We know that George Graham did, but that's well known and back in the 90s, so not sure if he's included in the "magic 8".
Reading between the lines, I would suggest they are relatively recent managers, i.e. within the last 5 seasons. Here is some dirt from the source...do any of the clues bring any name to mind?
Manager 1Pagliara claimed a former top-flight boss liked "bungs" in cash or deposited in a Swiss bank account.
He even stated he could call the manager at any given time.
Manager 2The Italian stated another ex-Premier League boss was now "whiter than white" - even though he has received a large amount of money.
Manager 3The boss is said to have been in charge of a number of British clubs.
Pagliara claimed he was fired by one of his former employers for having his "fingers in the till".
Manager 4The agent claimed the manager had plenty of experience in the Premier League.
Pagliara suggests he knows the boss "very, very well" and the accused asked if there was a "coffee for me" in the negotiations.
Manager 5It is reported Pagliara would often pay into a Swiss bank account to another ex-top-flight boss.
He claims the manager would call him to given him a number to the account.
Manager 6
The manager, a former player, is said to not be on a big salary at his club. Pagliara suggests he likes extra money to secure deals.
Manager 7Another former Premier League boss who was allegedly "on the pay roll" with the agents.
It is suggested the manager would receive money for taking players.
Manager 8A long-serving manager who would make his own players give him kickbacks in return for increasing their wages.
