@NathanOlder, regardless if Sky is broadcasting for British audiences only or the the whole world, a commentator must be as neutral as possible. Maybe Vettel has some British fans as well, maybe Max is loved by the British as well, so for example Martin must keep his balance when commenting, which he is most of the time, but sometimes you can feel and notice when the sky crew jumps in defense of HAM even if it is a absurd thing off track like once when I watched the Syk weekly report they were defending HAM's instagram post ect. So what I'm saying here is that I, personally don't want to hear the commentator cheer for Man.UND when I watch a derby game against Aresnal or Liverpool, I want them to be neutral, same with F1.
Again SKY F1 are the best and 90% of the time there are neutral so it works for me, I just hope they will cheer for Mclaren like they do for HAM....Just kidding
