Basically what I've been thinking Pep should do, Gundogan is phenomenal if he plays a little deeper, next to Rodri they were a fantastic defensive duo rotating duties of staying back or going forward.He was really good today. Really good. The tandem of Rodri and Gundogan is working much better than Fernandinho-Gundogan ever did and today they rotated who was the #6 and who pushed up, they were a complete wall in front of the defence, just mopping up every time the ball left the Dinamo half and getting it back to the forwards quickly.
With Mendy or Angelino as LB I think this systems works perfectly, but if Zinchenko comes back in then I think it fails, and requires a duo of David/Foden/Kevin in front of Rodri, to have a player to rotate with Sterling.
