Comment about keeping Fazio, cue rumours he's leaving. Always the way.
I've not seen much of Wimmer, so I can't comment on what kind of CB he is, but I am concerned that if Fazio does go, we're leaving ourselves with only ball playing CBs. I've always said the best CB pairings are made of one who sits a bit deeper and gets stuck in, and one who sits a bit further forward. You get the best of both worlds, and it's why Ledley and Daws worked, why Jan and Daws worked, and why Fazio and Daws worked.
I do feel sorry for Fazio. Possibly selling him after a season in which we made him play a high line and made him the scapegoat for any defensive problems when he was never the problem. Yet if you look at the games, we had a great record with him, and he was forming a very good, solid partnership with Jan. That pairing still enabled the fullbacks to get forward, and the rest of the team to press, so I'm baffled as to why we have not stuck with that, and yet again changed things seemingly not for the better (again!).
If we're sticking with Jan and Toby playing with this ridiculously wide CB tactic, don't expect a better defensive record any time soon.
Also, if we're continuing with Dier as a DM, it seems odd that we seem happy to leave ourselves with only three CBs?
