Well if this is going to be the case, Marmoush should have played LW in the CWC to give him some time to get to know the position. He didnt play 1 minute there I dont think, which suggests its not the plan…Having Ait Nouri overlapping will give Marmoush the space inside so he isn't hugging the touchline and Reijnders running in the middle should pull one of the center backs away to create more space for him.
I'm hesitant to pin Cherki or Foden on the wing because they both seem to do best just right of the middle with runners on either side of them. That makes at least one defender freeze trying to pick a runner or the ball carrier and those two are dangerous with that little bit of space on the edge of the box.
One of Cherki/Foden will need to take the right wing spot or the alternative is Savinho and that isn't going to turn out well!!
