There is something similar in FIFA career mode. Sometimes, when you buy a great player that plays in a position you already have filled (like buying an attacking midfielder when you already have one), there will be news articles about your current player feeling like his position is under threat. Then you'll get a message from him asking to be played ahead of the new guy.
Some guys will just ask for a transfer right away if someone else comes in.
Then, you have guys with a "team player" trait who will never complain about any of this stuff, and other guys who will act like a complete diva if they're dropped for one game. It's been in since FIFA 12 or 13 IIRC (could be wrong, didn't play much 10/11).
They're small bits, but they add LOADS when a star player demands a transfer out of the blue
