We have injury problems because he's incompetent. He's sold defenders during a World Cup year and hasn't bought any experienced ones in. He doesn't make best use of his subs and runs the first team into the ground until we're forced to make a change because of injuries. We'll bring in new tech to show players fatigue levels and he'll just ignore the warning signs. How many times as he said a players in the red but he keeps playing them? Ramsey, Wilshere, Ozil, Giroud and now Sanchez. He keeps playing them until they finally reach breaking point. He never learns!
