With Nani, Zaha, Kagawa and Welbeck reported either on their way out or already out - we have lost four wingers while gaining 0. I would say we have lost Young/Valencia as well considering LVG considers them unworthy of being played as wingers, which he stated as the reason we can't play a 4-3-3.
This means we have lost 6 players who were previously considered wide options in just this transfer window without attempting to replace them as Di Maria seemed to be a central midfield option.
Regardless of whether we want to play Di Maria out wide, with Januzaj or not - we will still be in need of some back up option. An injury to Di Maria, or Januzaj and suddenly we are back to being incapable of even fielding a 4-3-3 with two wingers.
Blind, Di Maria and Herrera is already good enough as a midfield as we are only aiming for top 4 in the league and we have a whole package of defenders now with Blind as an absolute world class third LB option behind Shaw and Rojo and Blind can also play RB if Rafael is injured.
Up front we obviously don't need anything - but out wide there is a gaping hole.
I don't think any of this will happen though as LVG seems stuck in building a 5-3-2 around RVP and Rooney in their favored position. I also think if he chooses to go this route we'll continue to drop easy points - while doing pretty well against the biggest teams.
