Look at it again and you'll see our tactics were all wrong for the players we had available. Without Munoz in particular there is no point expecting runs from both wing backs. Without Sarr, there is no out ball on one side. Hence, when you look back at it, Leeds marked Mateta - who already didn't look great. Pino runs down blind alleys so they stand off him - notice how there are always two or three guys in front of him in the end. That leaves Nketiah and he's not at his best out wide. He was largely isolated - the front three were not close enough together all match.
In addition, Wharton looked like he was under instruction to burst forward. It was nice to see. However, that left Hughes exposed in front of the back three. Leeds largely by passed that anyway by playing wide. They ran at Clyne in particular. Often, he wasn't there to run at. He was too far up the pitch. We were constantly chasing them down the wings and people were having to cover from the center. We were being pulled side to side.
A formation change could have perhaps countered that. But it didn't look like we were fully at the races anyway.
I'd say 4-4-2 or 4-4-1-1 would have let us progress through the middle and covered the gaps out wide. Even then, our approach was wrong. We should have been defensive but we were very attacking. We underestimated them and they not only out fought us, they also put thought us. Glasner has a tonne of credit in the bank but this was largely down to him.
