If Ole's man management was crap then he would have lost his job months ago. This team had bailed him out again and again, often with an individual act of genius. The reality is that every loves Ole. His players loves him, his coaches love him, his teammates love him, his former manager loves him and even Roy Keane loves him.
However love can take you to a certain level. Top players tend to want more then smiles, giggles and an arm on their shoulder. They want to show the world they are the best, they want the generous performances bonuses who are often tied to trophies won and they aren't easily dazzled by the opportunity of playing for Manchester United simply because they can or had played with top clubs already. If Ole can't provide that then they'll push for someone who could. Which is why Ole should have had his house in order in terms of coaching and tactics before signing the likes of Varane and Ronaldo. Players like him can't and quite frankly wouldn't wait for Ole, Carricky and Fletchery to complete their on the job training. At this point you can add players like DDG, Bruno, Pogba, Cavani and Maguire to the list
