Ugochukwu -Transfer becomes mandatory after 20 games - Concern

Guys,

So as far as we are aware Ugochukwu has a 25m transfer fee which will activate if he plays 20 games (some report 18, some 20, some 25)

Now my question is this, Okan has been putting this guy onto the field for eg, 10 minutes at a time, does that now count as 1 Game?

If so, i really do not understand why he is using up Ugochukwu games count and wasting them on 5 min playing time.

Especially if we are planning to send this guy back after the season ends.

Does that make sense?
