That's probably because Lindelof is scared shitless of doing any defending of his own. He always shift responsibility and blames someone else. Let's not forget that before Wan-Bissaka hit this bad run of form he was shutting down any winger down that side on his own. If players double up on him out wide while our central defence drops tight and deep to defend in the box, you can hardly blame him for not stopping every cross. In certain situations he is told to keep tight to Lindelof and in other games he is told to stay wide, yet the ball goes in the net either way, it's shit organising and passive defending, then blaming others for not making your job so easy you are able to do it.
I think he has played pretty well the last few games but the man is incapable of organising a defence and doesn't know when to push out and when to back off. He just always backs off, and before their last goal he had the ball at his possession but managed to rush De Gea out to take it from him for no reason at all, then he made the defence back off instead of pushing up when the ball was lost. Others made mistakes but he was the one who put us on the back foot for no reason, and just made us concede a goal out of nothing. No need for De Gea to kick that ball out when he had it, why was that the plan? If it wasn't either way it was a clear mistake by Lindelof, doing what he always does - shifts responsibility, backs off and blame others.
