His initial remit was basically just to bring Martial and Pogba back in from the cold and coddle them for 6 months. And he did that fairly well.
But now he's tasked with balancing a squad that's comically top heavy. And top heavy through his own awful squad management.
He's made promises to at least three forward players in the summer, to give them more game time, that he won't be able to keep. They will all be sick of him.
Now he also has to manage Pogba, Bruno, Cavani, Ronaldo, Sancho, Rashford and Greenwood to cover four positions and he's failing miserably at it. Pogba and Ronaldo have already turned. Cavani is probably a bit disgusted with how he's been treated, coerced into staying another season only to end up being Ronaldo's back up. Bruno is clearly going a bit stir crazy. How long until the English lads start to turn on Ole? Sancho already looking disillusioned. Can also see Ole religiously sticking with Rashford and Greenwood on the wings now as they are both very much "his guys", much like McFred.
