Yep, he's got a plumbing business to run, he should put that first and recognise that social media isn't a place for trying to make jokes even if they're well intentioned. He'd be better off making an actual point if he's annoyed in any way, which he doesn't seem to be.
I disagree about Brown, he wasn't even close to the best player on the park in our recent game and nearly all our midfield out performed him. I'm not expecting a lot from him and will be happy if he still has what it takes and hope that he adds something behind the scenes in his assistant role. I'd be extremely cautious about hyping him up if I were AFC, and if he's our marquee signing it's nae really that inspiring.
