PES 2021 takes a lot of it and uses it quite well, and you can see this with mods for it that allow all the potential in the game. Problem of PES 2014 is that animation blending is not too good, since it was not prepared for a football game (fox engine was literally developed for Metal Gear V), and it felt clunky for this reason. In real life you can change direction quite faster, and be much more adaptable. In newer PES 2021, maybe the quality of the animations are not so good as PES 2014, I buy you that, and there was not so many simulation of physics to the level of 2014 in the sense of complexity, but being less complex, it is much more polished, specially with mods.
For me, one thing PES2020/2021 did good was recovering the right stick control from PES 2014. There are some mod by
@TheProEvoManager that adds some .cpk to the download folder (you need to include it in the DpFileList) called controllerbody.cpk and TimeControllerBody.cpk that adds more gravity to the movements of the player and makes the movement really enjoyable and natural, making possible to walk/run/move quite realistically.
And ball physics can be also tweaked. Essentially, we have much more capabilities to tweak the game to our likings, and even we are now starting to be able to remove the scripting, and the AI is now much more complex and plays much more sophisticated and realistic, I'd say, without ping-pong passing and with ERRORS, instead of always passing perfectly to where you want. It is by far the best game I've ever played in that regard.
