He will be gone regardless. Once top 4 becomes mathematically impossible.
I just look at Lindelof & Bailly and see two players that are comfortable on the ball and are aggressive. They don't take necessarily touches like Smalling. I get that Smalling might look more safe but I don't think that helps a team that is so bad at building attacks at all. Having a defender who is willing to take risks is not a crime.
I am not suggesting we would water tight with Lindelof & Bailly but we would at least shift the ball around quicker and get it into the midfield and attack without passing sideways and backwards as much.
Maybe you have different expectations from what you want from a CB. But I think we will concede goals regardless because our team just isn't very good. I rather pick two defenders that have better feet and are comfortable passing forward.
Smalling doesnt look more safe.
He's a better CB
He makes less mistakes and is more consistent. He's also far better in the air than either of the other 2, which is 1 of their biggest weaknesses. He's also very good at covering players out of position which tends to be the case for the players he's playing with.
People list all the things Bailly has. Strength, speed, aggression... Yeah great Jones has all those things too. But why are people sour on Phil Jones? Mistakes. Perceived inconsistency (even though for most of last season he was quite consistent)
Being a consistent semi hard working CB who makes less mistakes than the others and reads play far better, able to cover for teammates on a regular basis is more important than physical attributes or being more comfortable on the ball.
1 good game from Bailly doesn't mean he wont have a mare in the next couple of games. Its not his issue that he cant have 1 good game. His issue is concentration, consistency and too many mistakes. That will take 10-15 games to show if theres much progress on that front at all. It might take a whole consistent season to show its really something thats no longer an issue. 1 game shows nothing.
Lindelof on the other hand isnt like Bailly. He's a bit more consistent but has also made several mistakes and he isnt as good as Bailly on a good day, but better than him on a bad day. You know a bit more about what you're going to get from Lindelof - which is a 6/10 performance while Bailly might be anything from 2/10 to 8/10
He isnt a semi hard working CB, he generally makes less actions than most CBs - I know because I've actually looked at these things. I look at the stats not just of our players but other players in the league in the same positions. He gets people praising him and calling him man of the match when he makes 1 or 2 good defensive actions despite doing less than most players in his position simply for not making too many mistakes in a game. Well when you do less stuff you're restricting the amount of times you might make a mistake. But someone has to do the work, so its more defending for others.
Smalling, Bailly, Jones and Lindelof should be competing for 1 CB spot next to a new CB. I have no doubts that Smalling should be starting next to whoever that is. But if Bailly does progress in the ways that he needs to I could see him having a run in the team too
