Goalkeeper Courtois emerged as a young star in Belgium with Genk, but was quickly snapped up by Chelsea in 2011. With Petr Cech firmly entrenched as the first choice goalkeeper at Stamford Bridge, Courtois was immediately loaned out to Atletico Madrid, but his impressive displays in the Spanish capital have seen this deal extended by a year - twice.
This season, Courtois has establish himself as the best young goalkeeper in the world, turning in consistently excellent performances for Diego Simeone's men, and last night they were rewarded with the La Liga title, as Atletico got the point they needed at Barcelona to clinch their first title win since 1996.
Courtois couldn't hide his delight at bringing the league trophy back to Atletico after almost 20 years without it, praising the work done by Simeone over the course of the season - especially when it was once again considered that Barcelona and Real Madrid would be the only teams vying for the La Liga crown.
"It's a fantastic feeling. I think that after last week, probably very few people believed that we could come here and get a draw off a Barça side that was going for the title. What we've done is incredible, no one could have imagined it before the season and look at us now," said the Belgian international.
His three year stay at the Estadio Vicente Calderon is coming to an end this summer, but his future at Chelsea is still murky with Cech in the picture. Manager Jose Mourinho has a decision to make, with both shot stoppers wanting to play regular first team football, and Courtois, 22, refused to commit his future to any club.
"I have a huge amount of affection for the club. I never could have dreamed of this three years ago and I'm really grateful. We'll see what happens with my future, there's nothing decided yet. Don't forget there's the World Cup coming up too. We have to keep calm and see what happens," he said.
