On April 30th 2017, Bayern Munich's option to buy Kinglsey Coman will expire. Ancelotti's club will almost surely use this option and buy him back from Juve before then. Bayern Munich will have to dish out 21 million euros to Juventus for the young French international (plus the 7 milliion euros that Allegri's club have already received for the two year loan). Let's not forget that Juve will also likely get an extra 16 million euros for Zaza's Valencia buy-back too. That's 37 million euros that will be coming in from players who haven't been with Juventus in over a year.
