I'm not sure you can argue that our depth has massively changed or improved. We have a few young players with good potential who "might" be an upgrade squad depth wise.Personally speaking, I’m not as high on Bentancur as others, Werner started vs Newcastle, Emerson started at LB vs Liverpool (Lamb to the slaughter vs Salah), and Kulusevski’s is not an Ange winger. You’ve just proved my point, in that last season all it took was 1-2 changes and it all went to crap.
As we never had any depth Ange could rely on, it became increasingly easy for the opposition to adjust to us.
Last year was mainly about finding out who can’t hack it and then getting shot of them. This year is where the real work starts with a foundation in place.
In the same scenario this season Bentancur will come in for Biss once again.
Spence will play at LB if Udogie is injured - that's very much an experiment at this stage and not a clear upgrade on Emerson.
Odobert ahead of Werner/Kulu as first choice wing rotation could be an upgrade but again we have little evidence to back that right now.
