Real Madrid have been in the race to sign Antonio Rüdiger for some time. The German centre-back has been amazing for Chelsea, and has now joined Real Madrid, with the deal being for 4 years. He had a fairly good season with Chelsea, helping them finish 3rd in the Premier League and make it to the quarter-finals of the UEFA Champions League. He finished this Premier League season with the 7th most passes.
Real Madrid had a great season, winning the Champions League and LaLiga. However, defence was arguably their weakest department, especially after the departures of Sergio Ramos and Raphaël Varane from the club. Therefore, Rüdiger can be of a lot of help to the current champions of Europe.
