Of course match fixing goes on in our top leagues, there are too many unexplained actions for it not to be true. Apart from Grobbelar there was that match at Everton that they won 3-2. Their third goal went under the keeper who takes his hand away at the last minute. Of course I can't prove it, but I was at Coventry when Bruce punched the ball into his own net.
I have only seen the 'highlights' of the West Ham - Brighton game but one team wasn't trying very hard.
