The agreement includes an option to buy the 24 year old defender and it looks like its just an optional purchase, not a predetermined one. Basically its the exact deal I reported on two weeks ago.
Now the club turns its focus on selling Mouctar Diakhaby in order to bring in another central defender, probably Jaison Murillo. In the meanwhile the club is going to continue looking for a big sale of either Guedes or Gaya, though the club might abandon that option if they can not get any sort of big money out of those two and go for the sale of Kang-In Lee for some 15-17 million euros as well as sell Cheryshev for few millions as well.
