This is the problem with owners who know jack about football but have lots of money. They don't want to invest, it's just about turnover.
Darren won't last long if he keeps failing to make subs. I question his ability to make key decisions. He seems like a nice guy, and nice guys finish last. He blathers on about a tough, busy schedule, but doesn't make use of subs.
And considering he was a defender himself, our defence is shocking. Usually the position the coach played in is the first to be improved. The reason you don't see a great number of GKs in management positions.
