In my experience (on PS4) teams stick to their manager tactics (works with custom ones) BUT managers do not necessary stick to teams. There is a manager carousel in PES (which is not really the case in the other game and I love that idea), so if Klopp moves to Eibar, Eibar will use the tactic assigned previously to Liverpool and Liverpool will use their new manager tactic. If the new manager comes from a team you didn't edit the tactic, they will use one of those screwed non fluid konami tactics.
I can't remember if I did long simulations of several seasons to check if tactics would stick properly to managers throughout the years though.
Yes i remember this. There was a "bug" before 2018, when i was manager in a PEU team and i leaved for an other team, due to my request and not by acceptimg a propose, my old club had a generic manager or a "clone" of mine, same name, grey figure and same tactics.
On 2019 i noticed for example Valverde in Barcelona had a 4-4-2 with 2 CF, but during year he got another formation , a 4-3-3 , due to myCLUB mostly, where same manager can have multiple "cards" versions-tactics, cause the tactics in mC are locked. So i noticed during the second season in ML, Barcelona having Valverde, was using both formations 4-4-2 and 4-3-3 , based on the criteria the AI picks the squad, form, fatigue etc. Their first formation was edited by me to be SS-CF on attack, to help AI make better squad rotation. In our second leg CL group match, they used the 4-3-3 formation (Valverde version). During mid season, when i went back to check Barca, they were still under Valverde management, but he used the 4-4-2 with CF-CF, (Valverde default).
Ofcourse this was PES2019 and maybe i am already off topic, cause 17's manager roulette system on ML was more archaic, then on 2019.
But i have a strong feeling that after 3-4 seasons most managers seem to use tactics more similar to the default ones than their starting ones. Speaking mostly about wierd spacing, positioning, the shape remains same.
