I feel like the #3, #4 are a symptom of #1 and #2. He doesn't challenge the aerial long ball / lets it bounce, so he has to backpedal a bit. But then I don't remember a single case where that resulted in a scoring / threatening situation, he usually deals with it 1v1.
Being passive in cases like that IMO isn't a huge problem, if you go in all guns like AwB and miss the tackle or foul the attacker you pick up a card or worse, let a goal in.
If you're able to mask #1, #2 (sort of like what Chelsea do with Christensen), he could be a very good CB. As it stands every single physical forward stands next to Lindelof and asks for the ball direct.
