Player Interaction: Dude, I Never Fined You!

So, for those of you who don't know, B teams in Spain are basically teams in the lower leagues. I sent down a back-up GK from my first team. After a league match, he wants to talk to me, and says this:

That's all fine and good, but Bilbao Athletic is an autonomous team from my Athletic Club squad, with its own head coach. Hell, I didn't know he got fined for anything, as I was never prompted!!! How the hell am I supposed to respond to him?!

"It won't happen again, I'm sorry" I suppose.

Then maybe you can talk to coach to say "oi stop fining players!" ? lol dunno.
