Real Madrid have announced the signing of defender Eder Militao from Porto.

The 21-year-old centre-back becomes the first transfer since manager Zinedine Zidane returned to the La Liga club, and has agreed a six-year deal with Los Blancos ahead of a summer move.

A statement on the Real Madrid website read: “Real Madrid CF and FC Porto have agreed the transfer of the player Eder Militao, who will be linked to the club during the next six seasons, until June 30, 2025.”

Reports in Spain suggested the transfer of the Brazilian was worth around 50 million euros (£43.5m) after Real Madrid met a buy-out clause which was set to rise by another 50 per cent at the end of the season.

Militao began his career with home-town club Sao Paulo before moving to Porto during August 2018. The defender helped the Portuguese champions reach the quarter-finals of the Champions League this season with victory over Roma.
