I don't think it 'hinges' on Walcott any more than Van Persie's departure does on the signings of Podolski and Giroud ... more in the way of insurance perhaps.
Reckon just as Grimandi said, we've aimed to cover ourselves in advance of the tougher negotiations this summer. We can cut our losses on the wantaways pretending to be torn.
With Oxlade-Chamberlain and Podolski looking like wide options who will be in the first team squad, and Wenger's habitual practice of tossing the likes of Ramsey and Rosicky out there, I'm just not sure we're short in his eyes.
