Zidane has quit for whatever strange reason. The market is only slowly forming (assume it's been up for a while before he quit, as there's been speculation for a while). I cannot quite get my head around that Pochettino and Wenger are the two frontrunners.
Wenger hasn't done anything for the best part of decade to warrant, arguably, the top job in football right now. I kinda, at best, get him being linked PSG who's still building a team and club at the very top table of European football, but Real Madrid not so.
I don't imagine Poch will stay at Spurs for another 10 years, but I cannot see him leaving right after extending either. I would go against everything else, I've seen from and heard about him the last years.
If and only if the above is correct, there must be value, and lot of it, somewhere else in this market. Whether as a bet or a trade. Problem is Real don't look like they saw it coming, so they may have no clue themselves where they're going. My gut feeling is Guti would be the obviosus choice for a few reasons.
I won't get involved just yet, but if anyone agrees and fancies it, there you go.
