Three - if you include his manager with the national team.I remember there was a stretch last year when Dome kept subbing out Mitrita, often for no obvious tactical or injury reasons. I remember he went a long stretch of not playing 90' in a single match. I figured he had to be more a a man management thing than a game management thing. He had been underperforming up to that point before he eventually started showing some consistent flashes of his abilities later in the year.
It may not be the best way to handle things, but you gotta be concerned that two managers have had issues with Mitrita.
I wouldn't be surprised if what's going on here is bigger than just Mitri not defending. When taken out of the starting lineup, he may have reacted poorly.
