That was no grammar lesson. That was just me trying to get a clarification so that the conversation could go on in the right direction.
Everyone has a different view on who the best player is and where he should be playing.
But you seem to want me to guess who you think the best player is and where his best positions is, instead of just telling me.
This conversation would go much easier if you didn't have me guessing what you think.
But I'll guess you're talking about di Maria.
Then we clearly have a different view on how to use him, or even how we should play.
You can't just put a player like di Maria in one position and say "here is your best position, therefor you should always play here". He is a player that can offer you different types of qualities in different positions.
When we play 4-3-3 he could play as one of the middle three or as one of the wingers. In both of those positions, he's one of the best in the world.
But as my first post was about 3-4-3 / 3-4-1-2 (or whatever you want to call it) and thats where you reacted, I'll try to explain my thoughts on that.
Did you watch the World Cup? And especially Robben?
When I look at the formation and how van Gaal uses his players in that, I think di Maria could do what Robben did for the Netherlands.
With di Maria further up the pitch we have someone who can run in behind the defenders. Use the space between the centre back and the fullback. We have someone who is dangerous on the counter attacks and that's something we have missed since Ronaldo left.
With Carrick and Herrera in the middle we have one who can spot the longer balls behind the defenders and one who has quick passing and movement. Herrera's forward runs into the box is something we need, especially against weaker teams.
Di Maria as the wider left-forward offers you speed, runs behind the defence and is one that can hit a good cross.
Mata in the middle as the playmaker and Rooney as the wider right-sided forward.
I don't see anything wrong with that.
If you however think that a attacking position in this formation has to be played by a forward, like van Persie or Falcao, I suggest you take another look at how van Gaal uses his forward players in this formation.
