Qwiss -- I do think we ask a lot of our LCB when we play Zinchenko, but that can be slightly offset with Xhaka playing a more reserved role. Not sure it makes sense to ask that of Xhaka at home vs Sporting though....
Personally, I'm concerned about playing Kiwior alongside Jorginho, Zinchenko, and Xhaka. That's a very slow set of players in front of a CB that is still coming up to speed. Probably best to play Gabriel if that trio is playing, and then rest Saliba, or bring Tierney (in a more traditional LB role) in to help cover Kiwior.
