Yep.
Lovren, Matip, Sakho, Toure, Gomez and Lucas can still fill in. I think he'll be happy with that. Then he can fix the more pressing issues of GK, LB, CM or wherever
Assuming Sakho is banned for part of next season, I doubt Klopp is happy with that.
Toure is out of contract this summer, no guarantee he's here next year. Plus, he's 35.
Gomez is 18 and has played a whopping 7 competitive matches for LFC and is coming off ACL surgery.
That leaves Lovren and Matip (who will be adjusting to the PL), with a midfielder who can fill in at CB as our only options.
I'm not going to turn this into a transfer discussion, but again, this emphasizes the point that a lengthy Sakho ban makes an already dumb decision look that much worse and potentially makes it that much more difficult for Klopp.
