Nonsense.
Would you rather have a manager who went out into the media and threw his players under the bus like some of other egotistical bellends?
Martinez wont do that to a player, and it's a strength not a weakness. What he does behind the scenes appears different to me. He's had issues with Distin and Mirallas and dealt with it. That's the way it needs to be done.
No, I'd rather have a manager who kept his gob shut, then quietly made the correct selection call ahead of the next game when the teamsheet was released.
