problem with the assignment

I can’t complete this objective because the game has set a confusing requirement. I don’t understand why I need to score five goals in five separate matches—within a span of 10 matches—or how the game determines when that 10-match window begins. Furthermore, the counter doesn’t track the goals scored; instead, it tracks the number of matches played. To be honest, I just don’t get how this counter is supposed to work. I have a Hungarian player, and I’ve tried scoring with him, but I hadn’t really paid attention to this objective until it was the only one left. That’s when I saw the "10 matches" requirement. If there were a proper counter, I’d know exactly what I need to do to finish it—right now, it’s not registering as complete, even though I haven’t reached the 10-match limit yet.
