Dont always agree with some of Pulis's football but i always think he comes across as a decent honest bloke and that interview confirms that.
If anybody can sort Berahino out it will be him, i bet he must be even more gutted as since Pulis came in it looked like progress was made, then he has hit outburst, i bet Pulis takes things like that quite personal.
I dont know but the fact Pulis was willing to sell him was so Saido did get the chance to play higher but also he probably knew at some stage, Saido would play the idiot again and he is now left with an extra job of trying to get him back within the squad, said it before but Pulis prides himself on the all in together, got each others backs, etc approach so last thing you need is some jumped up helmet messing things up.
