Doing a Chelsea save and have noticed a couple of things, the main one being the lack of Cesar Azpilicueta's name on our favoured persons list? Over 10 years at Chelsea now, club captain, won everything possible with us and is the definition of consistency and professionalism. I've been a season ticket holder for over 20 years and I think most of us hold Dave in the same regard as JT, Lampard and Big Pete at this point. If he's not in that top tier of legends then he's unarguably one tier below and should definitely be in our favoured people. I also don't appear to be able to arrange a testamonial for him.
Mason Mount should be a natural at CM, he's said as much himself in multiple interviews and played there all through the youth system. Here's a couple of examples:

Kalidou Koulibaly has an 8 for concentration? Seems incredibly harsh on a guy who has been one of Europes top centre backs for years now. Not sure if that's just literally based on that one game against Arsenal in 2019 lol, but here's an article comparing him to VVD in 2020 when he was linked to United and it shows he made one error leading to a goal, compared to VVD's 2 - https://talksport.com/football/756602/kalidou-koulibaly-virgil-van-dijk-napoli-liverpool-man-city-man-united/.
Another article about him here - https://tribuna.com/en/news/chelsea-2022-07-13-why-koulibaly-is-perfect-rudiger-replacement-3-key-reasons/ - points out that - "Another big Koulibaly strength is his concentration. He rarely makes mistakes: just three errors leading to an opposition shot in the past five seasons with Napoli."
8 concentration for a guy who made just 3 errors leading to shots, not even goals, in 5 years is mental.
Harry Maguire made 16 mistakes leading to goals in 2021 - covered here https://www.footballtransfers.com/en/transfer-news/uk-premier-league/2021-11-man-utd-news-how-many-errors-leading-goals-has-harry-maguire-made - and still has a 12 for concentration. By that logic Kouliably should have at least 40 concentration
I'd also echo what an earlier commenter said in that Trev Chalobah seems to be slightly hard done by, and Reece James 100% still has room to get even better. Could be one of the best right backs of the past 10-20 years if he carries on developing, and there's nothing to suggest he won't.
At the other end of the scale, Jorginho seems quite overrated. He is a great passer of the ball, but I don't think 18 is accurate. He often misplaces those crucial killer balls. 18 is something more like Fabregas for me, I think 16 would be fair for Jorgi. 15 for off the ball movements seems very high for a bloke who never gets forward lol, as well as 15 for concentration being on the high side too. He's got a mistake or two in him.
Finally, I think Chilwell should be a natural at LWB as well as LB. Not sure what your criteria for a natural position are but if Kai merits being a natural as a ST because he's been used there for a year for us then Chilwell is surely a natural LWB at this point.
