theyve had to put up with hansen barnes collymore lawro etc. its natural that top players usually end up going into punditry
last time I checked Hansem and Lawro worked for the Beeb, Barnes has worked for ITV, Channel 4 and 5 and Collymore (a surprisingly good pundit considering he's not particulkarly bright) works for Talk Sport
Sky would never appoint an ex-Liverpool player as a pundit. You might say Redknapp but Tottenham and Chelsea are the teams he supports - not liverpool who he never has a good word to say about
It's no coincidence that the people who own Sky are the same who own NOTW/Sun - in their ongoing vendetta against the people of Merseyside due to their tendency to vote Labour
