I checked just to confirm
Yes, UEFA officially abolished the "cup-tied" rule in 2018, allowing newly transferred players to represent their new clubs in European competitions even if they played for another team in the same season. [1, 2, 3, 4]
Under this regulation, clubs are permitted to register a maximum of three new eligible players without any restrictions regarding their previous European appearances during that campaign. This applies across UEFA club competitions, including the Champions League, Europa League, and Europa Conference League
I didnt realise it was that long ago.
