While recognising its on the official site, Irvine does come out of the Saido article on there very well.
I am one if those who thinks that the players don't have to say anything at all, so ultra positive comments like those from Berahino should be viewed as real support for the Boss.
One last thought occurs, as much as so many fans, me included, liked and supported Pepe Mel, there wasn't the same level of overt support for him from the players as I remember it.
