Firstly a disclaimer : Levy needs to be replaced for us to be successful on the pitch. Just because I think the 2 or 3 windows have been good does not mean I am a Levy fan boi and we could not do better.
Now, on to the latest window. I have been impressed with our purchases and loans the last 3 windows. Kulusevski, Bentancur, Bissouma, Perisic, Danjuma, Richarlison, Porro, Udogie - All the right kinds of players. If we signed two or three players of that age and profile every window we'll do very well in the long run. Conte and Paratici said it would take at least 4 windows to address the squad quality, and if we get a new GK and 2 x CBs this summer we're nearly there. I know a lot of fans want a creative CAM or better back up for Kulusevski (so we are more creative) but I think, if we are playing Conte's system he does not want them and the squad is (at at least was) being built to his specifications.
If there is a change of manager this summer, and Poch returned, I think he'd have more consideration for our young players (Spence, Sarr, Gil), and some of our loaned out senior players - Lo Celso (Argentina connection), and possibly Ndombele (Poch was the one that wanted him originally).
