Thibaut Courtois believes he needs to experience playing in the Premier League before he is ready to make his debut for Chelsea.
The 19-year-old goalkeeper signed for the Blues from Genk in the summer after an impressive season as the No.1 shot-stopper for the Belgian champions.
However, Chelsea immediately sent Courtois out on loan to Atletico Madrid to further his development, and he moved to the Estadio Vicente Calderón to replace Manchester United-bound David De Gea.
Courtois has certainly proved he is a 'keeper with serious potential, and has kept 14 clean sheets in 26 appearances in all competitions for Atletico this term.
At the moment, Courtois is only scheduled to stay in Madrid for one season before he returns to Stamford Bridge, although Atleti could attempt to extend the deal.
And Courtois certainly feels he is best served to continue his apprenticeship away from Chelsea; and preferably with another club in England.
"I think that before going to Chelsea, I have to play one or two years in another English team to discover the football played there," he told RTBF.
"After that, we'll see if I am ready to move to Chelsea. It's hard to say now."
