I thought at the time that this was a odd signing. An ex-Denmark international who is clearly talented ends up in non-league football. OK then. It seems pretty obvious the problem is his attitude or mentality, not his technical ability, which makes this nothing more than a gamble (which hasn't paid off).
We need to stop taking punts on players who have 'lost their way' and start signing ones who are desperate to get involved and stuck in. Alternatively, we could have just kept Crawford.
