Midfield additions leave LVG spoilt for choice

It was common knowledge that Louis van Gaal would be dipping into the transfer market this summer for a midfield replacement for the still brilliant, but nonetheless ageing and injury prone, Michael Carrick.
Boy, how he's done that.
So much so, that we're now, in fact, spoilt for choice when it come to the "engine room" of the United midfield. 

I'd imagine that we'll line up in a 4-3-3 ( Schweinsteiger as a deep lying central defensive midfielder, and Schneiderlin with either Herrera or Fellaini alongside), then Depay on the left or right, Wayne Rooney down the middle and either Juan Mata or Angel Di Maria the other side.

Alternatively, LVG could revert back to the 3-5-2 (shudder!) with Matteo Darmian and either Luke Shaw or Daley Blind as wing-backs, any three of Ander Herrera, Marouane Fellaini, Carrick, Mata, Di Maria, Schneiderlin and Schweinsteiger across the middle and Depay leading the line with Rooney.

I would also think that a rotation policy between Carrick and Schweinsteiger seems the most likely, as to play both together would give us bags of brains and know-how but lacking in legs and pace.
A 4-2-3-1, would, for me, suit the personnel we've got the best, with the two new recruits sitting deep and Mata, Di Maria and Depay "floating" around in space (interchanging) supporting lone striker Wayne Rooney.

This formation also seems a good fit as, at present, only Wayne Rooney seems the obvious automatic starting striker as, despite James Wilson's undoubted burgeoning talent, I feel he's not yet ready for a senior place in the XI on a weekly basis.

Quite where Carrick fits the equation I'm not quite sure, but it's possible that van Gaal will rotate him and Schweinsteiger (given that both can be susceptible to injury), or, as another option, use Carrick as substitute to use his experience and intelligence when looking to wind the clock down in important matches (similar to how Ryan Giggs was used in the latter days of his playing career). 

Either way, it'll be worth keeping an eye on the pre-season games as these may give us an early indication of LVG's set-up looking ahead to the new campaign.

One thing's for sure, and that is the fact that LVG will have a selection headache when it comes to picking his midfield for next season, but it's certainly not a bad one to have.
