Hey, I noticed this very weird player on the transfer market: Iordanis Kalathas (id 196161171).
He is 35 years old, yet he hasn't lost over 1 ball in speed/stamina. If you look at the training history, he started deteriorating, but then there is a period of over 1 year in real life, where he doesn't lose stats at all. Only recently has he started deteriorating again.
What explains this long period of no deteriorating at all and then suddenly starting to lose stats again?
