Cech is reportedly wanted by Arsenal and Manchester United among others after spending last season playing second fiddle at Stamford Bridge, but Courtois reckons the 33-year-old is still plenty good enough to be a top side’s No.1.
“When you look at the quality of Petr there is no doubt that he is one of the best in the world,” Courtois said.
“Our relationship in training was really good.
“I think we pushed each other to a higher level and I think we have seen in the games for Chelsea that if I was not playing he was playing and he saved the team as well.
“For me he is a fantastic guy. I worked really well with him. Of course I am grateful for the year that we had.
“If he stays I am happy. If he leaves I understand as well.”
