Bayern Munchen management never imagined that Toni Kroos would become a legend at Santiago Bernebeu. Bayern request for a salary increase that could not be fulfilled at that time made him choose to leave, and this step turned out to be very appropriate. Madrid seems to very often recruit players from Bayern, if the recruitment of Alphonso Davies is realized then it is certain that they will release Ferland Mendy to another club.
It must be admitted that Perez is very astute when it comes to player transfers, he is very discerning in seeing opportunities that benefit them. Players whose contracts are about to expire, relatively young, will always be his target. Perez knows very well where Madrid position is in negotiations. I mean Madrid has a high bargaining chip, and the player will choose not to extend his contract if he gets an offer from Los Blancos, exactly the same as their transfer plans for Mbappe.
Ancelotti seems to prioritize recruiting players who can occupy several positions, in other words versatile players. The aim is very understandable, because it gives him several options to experiment, as well as anticipate other players who are injured.
