All these talks of footballing triangles and how our defenders are overrated- yet our defenders have hardly ever got to to play with a CDM that plays at the top of a defensive triangle.

CDM
Likewise with our goalkeeper we have a very reflex based goalkeeper who stays on his line and not a goalkeeper who can act as the base of a triangle at the bottom of a pair of defenders. We dont get a triangle acting with our pair of defenders so we hardly ever get this. As simple as it sounds, it's TRUE because de gea is on his line and it shows during corners.

CB-CB
I've seen that some fans seem to think players like Christensen and particularly Zouma may or may not be your long term future CB's. Likewise many here are unsure of Maguire and Lindelof. However, alot of that insecurity comes actually from the fact that we have a Goalkeeper that doesnt bring the best out of our defenders. Now that you have Mendy it should be much easier for you to see who exactly is good enough to be your long term starting CB and this has started to show at Chelsea apparently.
I really hope that stability at GK comes at United soon because once that's there - seeing the dodgy CB's becomes easier to see.
