La Liga: Reviewing Real Madrid's summer transfer activity

#3 Defenders

Eder Militao has joined Real Madrid

Real Madrid signed 21-year-old Eder Militao from FC Porto for €50 million. Madridistas have seen Militao as the club's new Sergio Ramos. While Ramos is still capable of holding the defence, his form has somewhat reduced throughout last season. Also, Ramos is turning 34 soon, and having a capable player for the future - and even for now - seems like the best bet.

Another €48 million was spent on Olympique Lyon's left-back Ferland Mendy. The 24-year-old brought some spark to the Ligue 1 on the left-wing, and Zidane is clearly hoping that Mendy has what it takes to collect the baton from Marcelo. Marcelo may still keep his spot in the starting lineup, but Madrid will be glad to have a strong backup player on his wing.

Javi Sanchez gained his promotion from Real Madrid Castilla, but the centre-back has been sent on loan to Real Valladolid. His performances there will surely impact his position in the team when he returns.

Young left-back Theo Hernandez went out on loan to Real Sociedad last season. It was clear that the 21-year-old was surplus to requirements at the Santiago Bernabeu, so Madrid accepted a €20 million offer from AC Milan for him.

Both Sergio Reguilon and Jesus Vallejo have gone on loan to Sevilla and Wolverhampton Wanderers respectively. While it is uncertain they would have any future at Madrid, their loan performances may push their temporary clubs to buy them from Los Blancos.
