Loan system should be unlocked at level 6 to prevent cheating.

Loan system should have 3 types: week loan, 2 weeks loan and full season loan, as the owners can also call them back into their team for a few amounts of tokens if they really need them, such as when their players injured and no replacements available, or if the player is hardly performing there. Another thing is that players can't loan scout (6* or higher) players.
