This isn't hard. Claudio Reyna needs to come out of hiding and say "Look, we signed a pre-contract with Lampard and City signed him in order to help comply with FFP. We didn't think it would be a big deal but obviously we were wrong. Because we didn't think it was a big deal, we didn't share the exact details because in our minds, he was with NYCFC. That was wrong. We apologize to the fans. We're a new club, so we're going to make mistakes, and we made a big one here. We'll work in the future to be as transparent with the fans as we can be.
Furthermore, thank everyone who is still a supporter today. We know we haven't made it easy on you, and we appreciate you standing with us. That's the kind of support we'll need to reach our dreams, and frankly it's the support we haven't earned yet. We will do our utmost in the future to earn that support both on and off the field. To show our appreciation, we will do x thing (and thing involves NYCFC spending money on something for the fans). "
If n0t the above, just please shut up. You're making it worse.
