Lindelof will be in the squad and deserves his place, let alone his current first choice selection. Nobody disagrees that United can do with a better partner for Lindelof and/or Maguire.
But you slating Lindelof, as you have, which you cannot deny, is terrible on your part as a supporter and many others. There have been certain standards set by the great United teams, which is fine because it's part of the club and what it means to play for United, but if/when you're not at that level personally, that doesn't mean you cannot achieve that as a team.
Wes Morgan and Robert Huth won a PL title as a CB pairing. And you're right, I can write a novel because it makes objective sense while you can write a sentence that discredits you or shows you have some odd bias against Lindelof on more levels than some of your better contributions such as; you continue to say Lindelof cannot head a ball away or that AWB is better at headers than Lindelof which someone discredited you on that, AWB will not be a CB for a long time if ever, Lindelof is a championship player at best, you look down on AWB's height saying he's only about 6 foot tall all while only focusing on his sweeping up ability due to his speed and AWB is not a better header of the ball than Lindelof all while you're banging your drum about CBs having the best abilities to head the ball away, "there's not a ounce of attacking talent in this guy" your comment on AWB....and my personal favorite comment of yours -
"Jones has become a sort of a joke recently, but he has been quite a good player over his career at United."
Harry Maguire is a very good CB and is one of the best in the league. He's not perfect by any means but he's so far shown he's more than good enough for United. He's the club captain. He's not an issue, let's move on.
