To be fair though the manager is the boss. If he's not happy, it's his call. Who knows what goes on behind the scenes, so I can't say for sure either way.
Trouble is these days is that if players don't like a manager they use the passive aggressive approach. I can definitely imagine there are players in that team right now who want him gone.
If that is what Duncan suspected he was doing then I don't blame him, cause that sort of thing will ruin us...
But lets get behind him, because between Duncan and Keane, I can tell you which of the two, give more of a sh*t about Everton football club.
