Correct me if I'm wrong, but there is also No option of making a lobby for 2v2. Well at least that is what I've seen in the Online Modes lobbies. I hope I'm wrong because I'd like to see or organize a 2v2 league.
So now that we know that there is no Team Play option on FIFA14, I believe Pro clubs are the only solution in hand. I'm not much of an expert on this mode, but I believe organizing a game through it is a bit complicated.
Getting teammates together to play a match can be challenging at time. Via EA SPORTS Football Club (EASFC), you can now send messages to all Club members online even if everyone is playing in different modes. Teammates can navigate to EASFC in game, accept the invite and then are taken to the Match Lobby.
So this thread is open for ideas or extra info you might enrich us with to be able to see where we stand and what we can do.
