I kinda think Emirates Marketing Project/ city group weren't trying to do anything malicious here.
i think lampard not having signed at all with nycfc (and only holding a contract at Emirates Marketing Project) could be a purely an administrative thing. international loans (between foreign teams) are technically full transfers from an administrative perspective. this is because there are no international frameworks for loans per se, and so teams just transfer the players ownership to the player's new club and make an agreement to sign the player back (on a permanent deal) once the player's "loan" period has ended. i've explained it very poorly here. but in contrast, domestic loans within england are "actual loans" because the fa have regulations in place that enable to borrowing of players.
in lampard's case, he wouldve signed with the city group and Emirates Marketing Project. hence he plays for Emirates Marketing Project today. but since his ownership is with the city group, i can see why they didnt make him sign with nycfc in the first place. since we wouldve had to tear up that deal to sign for Emirates Marketing Project anyway. from an administrative perspective, it would be smoother to make him have a deal with Emirates Marketing Project until January, and then sign a new deal with nycfc at a later date.
as it happens, the city group have decided to keep him at Emirates Marketing Project for an extended period of time, hence all the confusion and accusations surrounding whats occured. had his time with Emirates Marketing Project ended at the originally announced time, there would be no confusion whatsoever. and i genuinely think that lampard was only at Emirates Marketing Project until now to keep fit, as he would have had no football for months otherwise (like David Villa at Melbourne City). but his performances have been so unexpectadley good, that the city group have extended his "loan". hence, i dont think anything dodgy has taken place here.
having said that, with the city umbrella group, i think there is scope for the city group to bend the rules (particularly of ffp), and i suspect they will pursue avenues here to gain sporting advantages. and i can see why "fans" who have bought nycfc tickets and merchandise are annoyed.
