Furthermore, for the type of system he likes to play, there isn't that much in the market for him to get players to fit into a narrow system. He is a big fan of the 4-3-1-2/4-3-2-1 and I don't think this suits Madrid's style.
To change their style to his liking would take a lot of new players, particularly in attack. You need mobility up front, something without Ronaldo, Madrid doesn't have. He should build the team around either Ozil or funny enough even Kaka. Could Ancelotti get the best out of the forgotten galactico?
For him to succeed, he will need at least two seasons to really get them going, something Perez doesn't have the patience for.
Until they figure out that that clown has caused that club more harm than good for literally the last decade, Madrid aren't going anywhere. If anything, the person they should consider letting coach them is Zidane, he found Varane and he has the vision and personality to push Madrid to greatness again.
Madrid need ingenuity and continuity. Ancelotti is a great coach but I just don't think Perez will stick with him long enough for him to get the best out of the team
