Perhaps i was a little strong with 'to accommodate Mendy'
My thoughts around this is that,
Mendy struggled to defend against brighton so gives him more protection
I doubt mendy will play in back four with Sane on the wing as others have suggested
Our LB situation is again dire, Delph showed against Spurs that he should be no where near the first 11
Zinchenko out
Laporte can play there but we then lose his calmness at CB.
Danilo can play there but you then lose that natural width as he will want to cut inside...
Might be worth looking at that formation, it also brings another central attacker in which may be useful.
I fully expect Spurs to go 3 CB's and wing backs against us in the return champions league game.
If Bernardo is still out or needs a few more days rest, we cannot play mahrez, he slows the play down way to much. With wing backs we then do not need wingers (sterling can easily play through the middle)
Sorry - that is a lot of thoughts!!!
