#4 Defensive reinforcements must be considered in the summer

Jesus Vallejo has been one of the most disappointing signings in Real Madrid's recent history, not being able to even begin to close the void left by Pepe and his No. 3 shirt in the squad.
Barely even being fit enough to establish himself in the rotation scheme, let alone the starting XI for the Blancos. He came in with lofty expectations after being one of the best defenders in Bundesliga for Niko Kovac's Eintracht Frankfurt, where he spent a season on loan.
Real must purchase at-least one central defensive player in the summer, someone who can provide both cover and competition for Varane and Ramos.
Especially the captain, who must be rested for smaller games in order to have enough gas in the tank for the big games, where his invaluable experience proves to be a difference maker more often than not.
