If Wenget drops Sanchez for this, he will have achieved his biggest WUM of the season.
We have to attack with Welbz, Sanchez and Oxlade to have a chance. They're all coming in to form, are pacy, tricky, hard-working and are potentially devastating on the counter-attack. Packing the midfield will just unbalance the team again and play into their hands.
I hope Wenfer is brave. Recent evidence suggest he won't be.
And play Diaby or Rosicky instead of Flamini. He's just completely out of his depth in every aspect.
