Cech says he kept in contact with Mourinho during his six-year hiatus but stresses the players had no inside scoop on his return to the Bridge. He is pleased at the reunion however.
"I only have great memories from working with him," Cech told the Daily Mail. "I am glad that we can do it again together. He gave me the chance to be the No 1 at Chelsea at 22-years-old, to start the season ahead of Carlo Cudicini. This is when my Chelsea career really kicked on."
Ask him what Mourinho brings to a team, how he manages to generate repeated success, and the answer that comes paints the 50-year-old as part master-psychologist part grand-illusionist.
"I think Jose Mourinho will always make you see what he wants you to see," Cech offers. "He knows a lot about his team. He knows how to speak to one player, to another player. He is careful the way he manages his team.
"The main importance of what I learned, you really feel, no matter if you played one or 10 games under him, you really feel a part of the team. You don't necessarily have to play every game.
"He is very demanding, so everyone really is on top of their game whether playing or not. You know that if you are not, you are not going to play. For every game he picks what he think is the best team no matter what your name is. It makes people really work."
