@Ragman,
There is too much money at the top level.
There was recently a probe into spot betting in football, where things like the amount of red cards, corners etc. are betted on .
There were plenty of takers but they were all from the lower leagues, those people whose wages are more in line with everyone else.
They even said there is no way the top players would do it.
You're right about money fixing results, the richest clubs can buy the best players and win the cups titles etc.
When Leicester won the premiership a few years back there was real shock because they're not one of the five teams who always win.
