Eyebrows were raised somewhat when Jose Mourinho sanctioned a deal to allow the long-serving Cech to leave for rivals Arsenal in the summer, but the Czech goalkeeper had fallen behind Thibaut Courtois in the pecking order at Stamford Bridge.
Cech, who won four Premier League titles, four FA Cups, three League Cups and the Champions League during a glittering 11 years with the Blues, was afforded the chance to hand-pick his next destination as a mark of respect for his trophy-laden service to Roman Abramovich's club.
The Gunners swooped for the 33-year-old for a reported fee of around £11m, as claimed by the Independent, and the shot-stopper has enjoyed an impressive campaign so far, recovering well from a shaky start against West Ham United on the opening weekend.
Cech was once again in fine form on Tuesday as Arsene Wenger's side reignited their flickering Champions League campaign with an impressive 2-0 win at home to Bayern Munich, and Green feels that the Gunners' keeper is out to prove he is still a top-class operator, despite Chelsea's decision to move him on.
Queens Park Rangers goalkeeper Green told Sky Sports News on Wednesday as part of their 'Morning View': “He’ll be looking to do the same at Arsenal and I think he’ll want to prove a point. And Chelsea were in a tough position with the form of Courtois and with his longevity, and how much of his career is left, so it was more out of respect from Chelsea that they let Cech go. He’s proving his worth for Arsenal.
“I think it was a difficult one for Chelsea to let him go. He had a difficult debut against West Ham, but you can see from some of the saves he makes, it’s fingertips stuff and they’re all fantastic saves.
“What makes him so good? His size, his stature and he’s just a very difficult man to beat in the game, and for being up there, he’s one of the best. I think he has broken the record for number of clean sheets and he broke all kinds of records at Chelsea."
Cech denied Bayern with a number of eye-catching stops at the Emirates as goals from Olivier Giroud and Mesut Ozil breathed fresh life into a European campaign that was threatening to fizzle out following consecutive defeats to Dinamo Zagreb and Olympiakos.
Wenger's men are still rooted to the foot of Group F but are now on the same points as Zagreb, who were beaten by Greek side Olympiakos on Tuesday evening.
Arsenal face the daunting prospect of travelling to Bayern in the next round of fixtures on November 4.
