I did see the game. I saw Lindelof celebrate when he cut out a routine cross. I saw him go for headers and not win some of them. The ones he did win I saw him not be able to direct and often go to the other team. I saw him being outmuscled and out-thought by an attacker half his size for the goal. I saw him not being able to step into midfield and initiate attacks. What game did you see?
The second goal we're defending a corner zonally, which for some reason means every fecker is nearer the front post (still getting beat by Bednarek who flicks on) while Lindelof is our only defender further back towards the far post. He has Obafemi with him, who as you say is short and so Lindelof could be hoping to beat him over his head if the ball comes straight in from the corner, he also has Smallbone and Bertrand to worry about to his left coming in behind him. He looks silly for this goal and is beaten physically, I won't deny it, but if he gets goalside as everyone is saying he should I wonder if he stills gets caned if the ball squirts out to the far post and someone toe-pokes it home? When a ball is flicked on, which Maguire himself in his post-match said was completely unacceptable, Lindelof has several worries to deal with and he must react very quickly, less than ideal for any defender I hope you would agree.
Elsewhere I saw him do some fine defending, he was congratulated by De Gea a coupe of times for if you like 'routine' stuff, if you'd rather our players didn't cajole each other throughout the game as footballers have done throughout history that's fine if a bit odd to me. WhoScored have Lindelof as winning 4 aerial duals, more than anyone on the pitch, and losing one which backs up my assertion it was a good display from him yesterday. I thought going forward he was ok, he stepped up now and again into the right channel and played the ball forwards a few times, it was nothing special but ok. I wonder if you've been into the Maguire thread to cane him about marking nobody whatsoever at the corner, perhaps not as he did step into midfield a few more times, though why it is particularly important centre backs step up in this game when we're 2-1 to the good, if anything we're trying to get them on the break as they're enjoying possession in the second half and in possession it is often Shaw who slots into midfield to provide the extra man as Pogba and Bruno take control isn't clear.
By the way if you have reservations about Lindelof's game and doubt he can be part of a first choice title-winning XI that's fine, I have the same feelings myself. But I don't see, other than some criticisms of him at the very end, where you have got the idea this game was a case study in how ill-suited Lindelof is to a team with our aspirations.
