I remember reading an article about manager styles and age of players.
It said that younger players in general need a more authoritarian manager, while older players (in general) flourish when given more personal responsibility.
I think that probably applies in many areas in life.
We know from other reports that Jones was not much of a disciplinarian. He got the best out of players like Bothroyd and koumas by giving them a degree of freedom.
I think he recognised that Matthews was struggling with this approach and attempted to react but when you're one way with the rest of the team but harsh on one guy it comes across as victimisation
