A Fast Trainer ??

[Celtic]

I just bought this player yesterday
Market Value :- 830 K
Wage :- 6 K



When i trained him for the first time today (Hard) His skill progress is as follows:-
Stretching :- 39%
Cardio - 92%
Practice match - 142%

So can i assume him as a fast Trainer ??

3 stars ans Quality 20? The only thing to do here is waiting till he's 1 star from 25 and selling him.
