Was going to answer these two remarks, but see that Totti has given a perfect summation.
Our downward spiral since February is largely that we ran CM into the ground. No options to rotate and they were knckered by season's end.
Top comment. I feel the regression at fullback is now our biggest achilles heel.
No wonder Kane had his lowest shots per game average last season, Dele didn't score as much and Eriksen had a so-so season.
Walker and Rose marauding forward, pulling defence's out of shape and formation and causing havoc as you say, was precisely what opened up pockets of space for Kane and Dele to thrive.
Now we can't break down a bus, and clubs like Newcastle and West Ham can come to our new stadium and grind out 1-0 bus park wins. Poch selecting Sissoko and Moura in these types of games doesn't help, they need room to move into. Just like in that last minute counter in the NLD and Sissoko's fluffed shot. They both need space.
We need to fix fullback.
Hopefully Ndombele and Lo Celso help forge a midfield that 'just worked' like the Dier and Dembele partnership.
