Thibaut Courtois says Petr Cech's departure marks a "new era" at Chelsea and does not want to be compared to his former team-mate.
The 33-year-old ended an 11-year spell at Stamford Bridge with a £14 million (€20m) move to Arsenal earlier in July, having fallen down the pecking order following Thibaut Courtois's promotion to first-choice keeper.
