Seven decades of Cardiff City v Huddersfield Town games.

[the other bob wilson]

2000s - given that Huddersfield only scored 5 goals against us that decade, guessing Dwayne Mattis.
2010s - Emyr Huws.
2020s - Looked on the Huddersfield official squad page and think it's goals by Jonathan Hogg.

You've got the 10s and 20s questions right, but the player in the 00s question scored just the two goals in his career, neither of which were against us.
