Chelsea boss Jose Mourinho insists there's no great concern over his future No1.
Thibaut Courtois, currently on-loan with Atletico Madrid, has warned he won't return to sit on the bench behind Petr Cech.
As for the choice of who will be first choice in the long-term, Mourinho said: "I think it's a good decision because I don't think many would disagree that we have the best goalkeeper in the world and the best young goalkeeper in the world.
"It's a very good problem. Our goal is safe and, financially, we are also very safe. Their value in the market is the value of the best. We don't have a problem. Teams without good goalkeepers have the problem.
"Petr came here after Carlo Cudicini had been voted player of the year. He came here very young and, first game, Chelsea v Man United, a clean sheet and the first of his book full of clean sheets. The guy is fantastic. Again, working ethic is amazing, the way he works and the way he lives. He's a very young goalkeeper at 30."
