I think for the remainder of the season the priority should be seeing which of the attackers realistically could work at Chelsea. I'm not sure a much better starting XI would have been feasible based on the current squad today, other than I would have definitely not started Kova on recent form.
Against Bournemouth I would bring Ruben into a 3 or simply move to a 3-5-2, Kova is offering nothing.
There was talk of Felix being loaned next season again. If this is the case, why oh why is Ziyech, who clearly is not going to be here long term, being substituted on ahead on him?
Lots of thinking to do and lots to digest. Basics like attempting some more long balls or balls in the channels when faced with high presses might also be worth a shot.
I was annoyed at 3-0, unfortunately it turned quite apathetic after a while
