Feel like we've opened the football version of pandora's box this year. Every single club is bargain hunting and that meant a bunch of players who probably would've otherwise signed contract extensions are not signing (Camavinga, Rice, Saul, Pogba, Varane, Depay ... the list goes on).
Not sure who comes out ahead when all is said and done. The players and agents will definitely benefit - I think more and more players will just sign the contract and run it down. Clubs will be forced to offer extensions earlier - so basically 2-3 years into a 5+1 contract you have to offer an extension or running down the contract becomes a real possiblity. Agents will make hay with all the signing on bonuses that come their way.
I think bigger / richer clubs will come out ahead as well. No incentive for players like Kane to sign a new contract on paltry wages.
