I think I disagree about Maguire/Lindelof but they do need more depth there.
They're not bad players, but when they're together they seem to be less than the sum of their parts. The pairing isn't complementary enough. They're involved in too many concessions, which is an overall defensive issue for United currently. Each would be better in a partnership where they're paired with someone with more pace since neither of them have a great amount of it. Also, Maguire seems to be sorely misused on corners quite often, and I'm not sure who that's down to. United's set piece defense frightens me much of the time.
When they had Maguire and Bailly paired up for the League Cup QF the flow was nice; the FBs weren't tucking in and were bombing on more like they're supposed to. The two CBs were pretty much on their own; how often does that happen for United lately? They've tended to take too much of a protective stance with Maguire/Lindelof this season especially; the FBs end up tucked in too often and too often there are two CDMs, which is inhibitive to the attack. The coaching staff really need to get the situation at the back sorted, as it was a big contribution to their Champions League exit.
