I have a couple now as I've aged and mellowed slightly.
I only ever talk about 'old' footie with them...terrace antics etc back in lively times, this works really well.
They know better to ever have a pop at current City but will moan like fuck about the state of the rags, makes me all warm inside.
The only other one I know is a lad I worked with in the 80's who is part of my main mates group, again I never comment on anything football on our group WhatsApp group..... laughable comments in there from any none blue however, they're good lads.
