Six month contracts, the clubs can terminate at every transfer window. If the players can just walk away, the clubs will find a way to do the same. No more running out your 5 year £300k a week contract, you’ll be out.

Smaller clubs will not pay as much, and probably give up on academies, as you can just poach for free. Players below top-division level are going to find their wages decrease, dramatically I imagine, and the European Super League is a reality.
