Atletico Madrid’s starting XI at Chelsea cost just 35 million euros!
Lest we forget, Fernando Torres was purchased by the Blues for 50 million euros.

Chelsea paid 21 million euros for Nemanja Matic in January – Atletico’s most expensive signing in the starting XI at the Bridge was Arda Turan at 12 million euros.

Intriguingly, over half the 35.3 million euro today was spent on the Atletico Madrid defence. And, a hugely impressive youth system at the Vicente Calderon should also take a lot of credit.

Reaching the Champions League final in Lisbon is an amazing achievement for Atletico Madrid – perhaps only comparable to FC Porto reaching the final in 2004.
