The last 30 months have seen young 21-year-old Belgian international goalkeeper Thibaut Courtois  emerge as one of the best keepers in Europe.
Having been sent on-loan to Spanish La Liga club Atletico Madrid  for now the third straight campaign, the keeper has made over 125 appearances for the club and has recorded a host of clean sheets worthy of any highly rated international first team star.
At his young age, Courtois has been a part of Atletico's most successful campaigns in years having won the UEFA Europa League and UEFA Super Cup in 2011-12 and the 2012-13 Spanish Copa Del Rey last season.
Equally on a personal level the 21-year-old became one of the youngest recipients in the history of the Zamora Trophy (awarded to the goalkeeper with the lowest goals to games ratio), as well as being only the seventh non-Spanish player to win since 1928-29 and the only Belgian to have won the award.
With so much time being spent at Atletico, the club approached Chelsea  this week in hopes of striking a deal to bring the player to the Vincente Calderon permanently after two-and-a-half campaigns of wishing he was their own.
However, reports from Sky Sports claim that Atletico President Enrique Cerezo is keen to see Courtois as a real Atletico player, but believes that Chelsea's valuation of the player is too high.
Courtois is still yet to make his debut for Chelsea as Pter Cech is still well in the prime of his career, but there is no doubt that the Blues see Courtois as their future and he is not likely to be sold unless the Spanish side come up with a massive offer.
