For Conor to get the England call-up was absolutely amazing and to make his debut was obviously even more amazing," Cech told
Chelsea's official website.
"If he didn’t go to Crystal Palace and perform but rather stayed here and maybe didn’t play every game then that would never have happened.
"Once you start to play regularly in the Premier League and show what you can do, that gives you all these chances to be selected. If you have the opportunity to do it when on loan, you can come back to Chelsea in a much better and stronger position.
"Conor will come back to us in a completely different situation than he was six months ago and that’s the beauty of it.
"If everything works out perfectly, this is the idea behind it and obviously it’s great to see that it’s worked out perfectly for Conor so far."
