You just need to ask the average Oxford fan what they think to Wilder to realise he isn't some sort of new Messiah and did strike lucky with that great season.
I reckon he thought the same and cashed his chips straight away to join a club with the budget that is more likely to continue that success.
Knill's free kick routine was great to see but come on, it was hardly revolutionary, clubs try plenty of similar routines on the training ground and some making it to games. Do you really think no-one has thought of a couple of passes with a runner before?
You do need plenty of skill and knowledge to be a professional league manager but the problem is all clubs have the the same skilled manager in charge. Unfortunately for them it's a league so they can't all do well, so it has to be something else that makes the difference and you can guess what I think that is.
Cashed in his Chippy surely?
