Arsenal need to set a final price and date for Bellerin: Betis completes deal to pay a nominal fee by August 11th or all three parties move on. Bellerin can then consider other offers or fulfill his contract at Arsenal. We need to take a stand and stop giving players away for free. Arsenal is rich enough to absorb his salary for one more year to make a point.
That doesn't matter at all when Bellerin seems willing to pay himself just to cancel the contract and escape Arsenal.
