I really don't see how they have a leg to stand on.

Be interesting to see how this goes to be honest.

Edit: In theory and I could be talking out my arse here but couldn't this set the precedent of doing this for player sales. . . We want say Saka, and offer £10 million. Arsenal who have him on a long contact so "no thanks, he'll be £100 million". Can we then take them to arbitration.

That seems same scenario?
