Great Game by a Player, but not so great classification

[Ricardo Napoleão]

Now, explain me this please...

(The images contain portuguese text, but the translation is the following).

My player N Tsvetkov was playing in the start eleven. Then on the second half (68 m) I made a substitution, replacing him by another player. The game comment was "Great game by Tsevtkov, he leaves the field and Risso enters in his place".

A greate game, is a great game. That should be reflected on the final game statistics.

For my big surprise, Tsvetkov classification was 4 (four)!

Now explain me this...
