Which club would realistically be stupid enough to match those wages? PSG possibly the only option. All other options would require him reducing his wages significantly I would guess because he hasn't exactly set the world alight during his tenure here.
Completely agree, but I'm assuming that he and his team thought he'd have loads of clubs knocking down his door for 400k+ a week, but he can't even get them to offer him 200k a week plus a decent signing on bonus (say 20m for a free transfer) - which would work out at roughly his current wage.
He's probably been offered 200-250k a week all in, which even then its too much, but hey, he's free so he may get that much (which is still a pay cut).
At the end of the day, his main asset is the fact he's a free transfer, and that should hit him like a train.
