Regarding Bailly vs Jones.
I’ve always rated Bailly highly even in the periods where seemingly everyone didn’t rate him. It’s clear to me that his top level is significantly higher than for instance Smalling. Now, he’s someone who needs games to get into that sort of form where he doesn’t make those mistakes on and off the ball. I’m not sure he has had enough games yet after his recent injury, but I believe there shouldn’t be any issues with playing him against PSG. He has the pace to match Mbappe, and the defensive presence to deal with PSGs attacking play.
I gave up on Jones a long time ago, but I have to say that his recent performances has made me reconsider him. I thought he was around 28 years old, but just realized he’s only 26. There’s a heck of a player in him somewhere and we keep seeing glimpses of that every now and then. I remember our games against Real Madrid in the CL in was it 2013? I think he played as a defensive midfielder in the away game against them and he was so dominant. One of his best games ever probably. That proves that he has got the mentality, and obviously the experience, to play in games like the one tomorrow. But then again, I can see Mbappe embarrassing him. Jones has previously had a tendency to end up in areas where his weak pace has been exposed. He wasn’t that slow 6-7 years ago, and it’s a bit of a worry if we play him that we’re going to press high, Jones is out of position and ends up 1v1 against Mbappe similarly to when Mbappe destroyed Rojo during the world cup.
Bottom line; I’d prefer Bailly, but only just. Jones has improved a lot lately and has proven to be someone we can rely on in big games.
