Top 5 biggest spending European Clubs of this transfer window 

#2 Atletico Madrid - € 243.5 million

Joao Felix

Atletico Madrid surprised everyone when they signed Felix for €126 million. With just one signing, Atletico made a strong statement to their domestic rivals who have been very active in the current transfer window.

Diego Simeone has always been happy with what he had. Despite the low spending capacity of Athletico Madrid, Simeone has proved to be a winner in recent years. Winning Europa League, La Liga and making Champions League final are few of his achievements.

Athletico made a switch to their new stadium last season. Usually, clubs across the globe struggle financially after such moves. Athletico broke the pattern as they have spent a total of €243.5 million this summer. The signing of players like Trippier, Llorente will boost the strength of Athletico Madrid for sure.

However, it will be interesting to see how Athletico will get better of their biggest spending domestic rivals.
