Theres no telling how many unlikely choices players make in choosing clubs in real life that you just never get the chance to hear about. I know the game doesn't take it into consideration but if I was Banega I would probably rather go to a team I know I can solidify a starting spot on for several years rather than a team who tells me so and I'm the starter until a better player comes along, have a bad run for a few games, or get loaned out to a poor club.
I had no troubles signing Banega to any team though, hes currently on my Betis (signed 2nd season), Aston Villa (signed 1st season), and West Ham sides (signed 1st season).
