Appreciate the feedback and its not a dig at Nick as its a lot of responibilty for one researcher which is why open discussion should be encouraged for users to share input. As stated downgrade of these 2 is probably warranted, Garnacho is not an issue for me as he's only broken into 1st team so it is too early to asses at this level. However there was few posts on the data issues section in regards to a case for the likes of Dalot (performance/match ratings have much better in last 6 month not only for Utd also Portugal) to warrant some changes. He has the same CA rating as FM22. Cases for Martinez in terms of his tackling ability, Jumping/heading (vs real world stats for ariel clearances), Mentals seem fine apart from determination (12 seem very low, drive and passion to the cause seem evident in the games so far to suggest its part of his personality). hopefully a few more months and it can strengthen the case for the winter update.
compairing a few CB you can from fbref.com he has attempted more tackles vs. dribble past attempts with a high success %. Take Saliba or Gomez on similar % and they have tackling of 15, Koulibaly has 17
As for heading or more so the jumping side comparing his closest Koulibaly has 16 & 15 for jumping and heading and Saliba is 16 & 16
Just some food for thought in the interest of discussion. But its only my opinion
Thanks guys.
