If he was notably bad in the air in that game you would have remembered it and certainly, others would have and would have made a big deal over it because, like Lindelof, there are always many people waiting for Bailly to make an error. I mean, just look at the way he has been criticised over things like taking a knee in the neck from his own keeper, or having Fred shoot the ball at his hand. I'd imagine any other player gets a pass in these instances.
And yeah I wasn't thinking of Maguire, more of Pogba and AWB. I did think it very unusual for a CM to be in that position but he was in it and should have seen it through, and to be fair he was going to, and he only stops because he thinks he's playing Lookman offside not because he's passing him off to Bailly. I would have expected Bailly to get tighter seeing that Pogba wasn't tracking well, however.
AWB is on the other hand, clearly out of position doing nothing. Should be concentrating much better.
But overall it seems like your criticism is more in the context of Lindelof vs Bailly and in that respect I would have to say I don't think Lindelof is a bad player. He's been very good this season and was certainly so against Liverpool.
