At what age will the PA drop?

I bought Ronaldinho at age 31, just wanted to know if the PA will still increase or decrease?

PA can't increase or decrease. Only CA can increase and decrease.

oh i mean CA sorry

Well it depends on a lot of factors. But of course that his CA can still increase or decrease. most likely that it'll decrease. But, as I said it depends on a lot of factors.

Physical attributes will start to drop after 30-32 depending on position, so there will be some drop from then

Yes, physical attributes will drop, but this is sometimes coupled with a rise in mental and technical attributes, if the player is playing regularly. Ade Akinbiyi's attributes have been improving for me, and he's 35.

If the position needs more physical ability, the decline will be earlier, while positions that are based more on a mental or technical aspect can last a while longer.

As said, PA never drops, but the "highest attainable CA" will indeed drop, thus becoming some sort of "new and lower PA"...

That happens in the early 20s, around I'd say 21-23 for players with average mental/hidden stats who aren't getting enough quality football and training.

Of course that may vary, and it's something you can be sure about just by using FM GenieScout, but also can be found out by judging the Scouts/Coaches/AssMan reports about a player.

If your former Hot Prospect is now 23 and rated as "useful player" it probably means he has "lost" the chance to reach his original PA.

Think of Francis Jeffers...
