I want to watch the team that Herrera, Di Maria and Shaw can play well in. That's as true now as when we bought them. If LvG doesn't want that kind of team, I'm honestly baffled by what he does want and even more baffled by his transfer decisions.
Di Maria as winger was always inconsistent at Madrid, capable of brilliance in the buildup but usually disappointing in front of goal. If we wanted a goalscoring winger/wide forward - he was never that player (were we even in for Sanchez). If we wanted a tactically flexible, hardworking flair player capable of devastating play, backed up by the necessary discipline to cover wingers/fullbacks on the move then that's where he picked up his "world class" label and price tag.
Herrera is a pass and move player, a terrier when it comes to recovering possession. He needs players to play one-twos with. If we want someone to hit it long to a wingback who looks knackered, he's not your guy.
Shaw is a young high quality prospect who had already proven his defensive skills, but needed to develop his attacking game. Now he's a disappointing wingback.
Yes, I get the good player should be able to play anywhere total football/er vision, but deliberately playing players out of position just looks like trying to make it harder for the new guys to deliver.
