If I was Smith I would keep my big fat month shut as he's basically digging himself into an even bigger hole by confirming he doesn't know a basic law of a sport he is paid very well to manage in professionally.
If I was his employer, I would be asking him some serious questions as to why he didn't know the rules.
John Moss clearly knew the rules as did the linesman and the VAR officials and City players.
Numerous posters on here including myself knew this rule too and we don't make a lucrative living from the sport.
Walton, Camelgob, Humphreys and co basically showed the whole country what a bunch of biased, clueless no nothing wankers they really are with their inane ramblings and personally I found it hilarious.
The whole thing reminds me of dealing with a clueless bullshitteer at work who has fuucked up and instead of coming clean has tried to cover up their mistake and dug himself into a hole so big that they cannot get out of it.
