He wouldn't really be a coach though would he? He'd be earning his badges while at Hibs I'm assuming?
He does however have a few tricks he could teach some of the lads though, seems pretty professional in what little I honestly know about him, freekicks are helpful and I think we could nurse him through a season if he's struggling. He managed to survive his short spell here but immediately got injured returning to Celtic I think?
Coach or no coach, if he isn't getting paid when he's not playing it's not a bad deal. I don't think these contracts actually exist though do they? It'll be a basic salary with proper bonuses instead I'd guess? A good player on his day but I agree there's younger players out there that can play week in week out and grow into a player with gametime. He's not gonna get any better and the likelihood of missing a huge part of the season is a serious risk... The chances of us signing him and then nobody proper to replace him during any spells on the sidelines would be a worry for me too.
