flobaba I just did one of Partey vs Rice passing stats for last season. Rice looks stronger in most respects.
Not according to the same website for both players across the 22/23 PL season.
Partey has a higher volume of passes per 90, has quite a higher number of progressive passes (through balls, passes in opposition half, and forward passes) as well as general passes (forwards, backwards, left, right etc like you'd expect from a "metronome"), he has more duels attempted (arial and ground), more duels won (both arial and on ground). Partey even has a higher number of takes ons completed per 90 and more than 20% higher success rate in doing so. He also won more than double the number of free kicks.
Rice has quite a lot more long balls and crosses attempted and completed than Pertey, is also completes more own half passes than him. He has a slightly better passing accuracy (87.98 vs 88.05) has a lower rate of misplaced short passes, concedes only half the number of freekicks as Partey and has more clearances, interceptions and blocks.
Rice is a good player who may even step up a level after joining us, but Partey, when fit and on form, is one of the best CMs in world football. At pretty much almost every aspect. If we replace him with Rice, it'll take some tweaks and changes to get us to find a way for it to work but Partey brings a huge, huge amount to our game.
