Hmm... I can't find anything online, and it really would be a fucking surprise, but I imagine old Didier still has a bit to offer. He's 34, so he won't exactly be flying down the wings, but he's not exactly geriatric.
This article (published yesterday) seems to be saying, from what I can gather through translation, that he left his current club this week, after the Chairman went a bit mental and basically sacked the entire squad, and backroom staff, so that they can use Youth players instead.
So, without wanting to throw fuel on this massive rumour fire, it looks like Didier Agathe is very much a free agent, and is still interested in playing football.
So... who knows?
