It's the co-commentators who need changing. Who gives a shit about listening to the following: McPointy, Hoddle, Hinchcliffe, Beglin, Murphy (these 5 off the top of my head). Carragher (bad enough as a studio pundit) could never be a co-commentator because I, for one can't understand him, it always sounds like he is clearing his throat. There are at least a couple more who are just not worth listening to, either utterly boring, talk shite or just state the bleedin' obvious, and most are biased and it shows through.
There must be a few ex-footballers or even managers out there who would add some interest to the commentary, cut the bias, talk sense and generally make comments more relevant to the actual match they are covering. They could also temper the bullshit that the likes of Tyler, Darke etc inanely spout, and who simply feel the need to fill any pause with their own voice talking for talking's sake. As a comparison, just listen to any Arabic commentary, those guys don't come up for air, press that mute button ffs.
This all leads to the question, who and where the fuck are they?.
