He isn't a gamble to get to where we need to get before that next step. We've gone through three managers woefully unable to deliver that. If in three years we are constantly third but despite more resources and a greater backing we are hitting the same brickwall then sure, get in someone else for that but they won't find a side used to just crossing the ball 479 times a game, or one passing the ball around aimlessly, or one setup to not concede against top teams. You won't have the problem that the previous manager wanted their left CB to be left footed while the new one wants him to be built like a brickwall.
I'm more confident in Ole picking up that side in 2-3 years and making it a winning side than I am on him building it, simply because he has no track record whatsoever of doing it.
Of course, regardless of managerial candidate, the elephant in the room in all this is the friggin' DoF and whether we are doing anything to get one in.
I stand by that, they may be poorer versions of the starters, but they slot in nicely without breaking your rhythm and style of play. Replacing Lingard with Mata and Martial with Sanchez is a fecking disaster. Nothing to do with individual quality differentials and everything to do with being completely different players.
