Simply looking at what Wenger is saying about the market over multiple seasons he does seem to imply he's often 'waiting' for an opportunity as opposed to creating an opportunity - solely based on his statements.
I guess I don't place any weight on what Wenger actually says. If he had it his way, he'd never utter a single word about potential transfers, it's only the media questioning that he's responding to.
Arsenal as a club prefer to keep it under the radar until signings are made usually.
