It has to simply fall with the manager.
Ferguson in his last title winning campaign, dragged a team loaded with Phil Jones, Anderson, Tom Cleverley and Rafael and won the league by 11 points.
This side is a side capable of winning the league, their depth, their quality is there. But where Ferguson could get away with dropping Ronaldo, Rooney, Beckham etc... and still win, Solskjaer can't.
His handling of Cavani, Sancho, Lingard and Van Der Beek are prime examples of how dreadful he is at man management. He's got a load of Square pegs, but not enough square holes, and he can't shoe horn 11 attacking players in. Sancho will go down a Lingard route I reckon, and end up with rock bottom confidence.
During the game, possession wise, solid. Quick passing movements, and find space, but defensively, they're so open, and we picked them apart 4-5 times in the second half alone, and their game plan really benefitted our system, so much so that we should have won.
Solskjaer failed at Cardiff, and whilst he's grown as a manager, I don't think he can handle it. But the question, if he were to go, what International manager is brave enough to take one of the biggest poison chalice roles, in World Football.
