Chelsea number one Thibaut Courtois has committed his future to Stamford Bridge with a new five-year contract, the club have confirmed.

The Belgium international returned to West London this summer after impressing Jose Mourinho during his three-season loan at Atletico Madrid.

The 22-year-old Belgium international was said to be uncertain about his long-term future at Chelsea should the manager not guarantee him the number one shirt ahead of legend Petr Cech - with Atletico monitoring the situation and trying to prolong his spell in La Liga.

But after the boss handed him a starting role in the first Premier League games of the season, Courtois has decided to commit his future to the club with a new five-year deal – even though he was already contracted with the club until summer 2016.

"Chelsea Football Club is pleased to announce Thibait Courtois has today signed a new five-year contract," the West London club confirmed in its official website.

The goalkeeper joined the Blues from Genk in 2011 and returned to Stamford Bridge this summer having spent the previous three seasons on loan at Atletico Madrid, where he lifted both the La Liga and Europa League titles. He was also an important member of the Belgian side that reached the World Cup quarter-finals in Brazil this summer."

Courtois has expressed his delight about the new deal, saying: "I'm very happy with this new deal, it's really nice to have signed this new contract for five years.

"My future was already sorted but it's nice to know I'm going to be here for another five years and now I can just concentrate on playing games."

Courtois won the Zamora award for Best Goalkeeper in La Liga twice during his three seasons at the Vicente Calderon while leading his side to a Champions League final, one La Liga title, a Europa League crown, a European Super Cup and the Copa del Rey.
