Dont think he had a bad game in the slightest, in fact I think he was vital as the only one who had any chance of defending in such a highline.
Would be a major mistake for Dias to come in for him. Take out our fastest centre back for our slowest and still playing a ultra high line would be suicide. It's Dias or Guehi alongside Khusanov imo.
Not impossible to imagine them as a back 3 with ait-nouri and Nunes as wingback if we want to properly adopt a 2 man strikeforce. That back 5, two from haaland, marmoush and semenyo upfront, a cherki/doku/foden/reijnder in the hole and 2 central midfielders from rodri, nico, bernardo and O'Reilly or perhaps 3 in tougher games.
