I'm not sure I buy that, he's been involved in professional football for 20 years (including international and Premier League football), he'll have had media training. Like someone else said I think he's just a bit of a grumpy bastard
It's good that he's defending his players and it is a lot more enjoyable than the corporate nonsense that gets trotted out in football (including by Morison/the club when we sign someone), even if his style can be a little detrimental/odd at times
