World Cup Football ≠ Club Football
That said having a target man is nice to have, but more than that we need a versatile, fast, clinical striker.
Will address your post LordLicheinstein later.
As expected.
You have simplified football into pace and mobility now.
A perfect midfield would have a mix of technique, pace, strength, aggression.
And some height.
You moved to technique, pace and mobility now.
Compared to Rm, Casemiro, anyone?
In attack, some journos explained why Giroud played. To draw 2 defenders, hold on the ball and open more room for Griezmann and Mbappe.
And to offer some physical presence in the box, headers after crosses as a plan B and some defending.
All top 4 world cup teams played that way.
And Rm played that way and won.
Not because of a mighty mobile Isco.
Now you picked technique and mobility again even for a Cf.
Look, your idea is better than the current Barca.
But it is probably not good enough for the biggest things.
So, please, try to add more factors in your midfield and attack except technique, pace and mobility.
