Thibaut Courtois
Courtois has never made an appearance for Chelsea.

Chelsea loanee Thibaut Courtois' future at Stamford Bridge is growing increasingly uncertain after the Belgian international admitted his future on loan at Atletico Madrid will be settled in the new few months.

Courtois has excelled in two-and-a-half seasons at Atletico, last season keeping the most clean sheets in La Liga while he has been an ever-present during Belgium's successful World Cup qualifying campaign.

But with Petr Cech, 31, deemed as the No.1 at Chelsea, Courtois' opportunities are unlikely to be frequent should he return to west London.

At 21 years old, Courtois' career requires some stability and both Atletico and Barcelona have been linked with a permanent signing.

And Courtois has warned potential suitors that his future next season and beyond will be decided in the coming months.

"It is not certain," Courtois said. "I'll see in a few months where my future will be."

The ex-Genk stopper would risk stagnating in the Chelsea reserves if he returned to the Premier League as Cech's understudy and with no guarantee of first team football.

Similarly, Chelsea risk losing one of brightest 'keepers in Europe should they not find a resolution to Courtois' career looks increasingly likely to be away from the Blues.

Reports have suggested that manager Jose Mourinho has blocked a potential move to Barcelona for Courtois, whose current deal with the club runs until 2016.

Having enjoyed significant success at Atletico, a division regularly referred to as an equal to the Premier League, Courtois might consider his future could lie away from Chelsea.

And despite Atletico being outsiders for the title, Courtois is satisfied by the challenge presented by the Spanish giants.

"Can we win the title? Not yet, it is too early," he admitted. "If you asked me with five games to go before the end of the season I would say yes we could, but not now.

"Is the Liga boring? I do not think so, there are three teams fighting for the title, and each of them plays good football."
