He was once a darling of Chelsea fans and a Stamford Bridge favourite but all that have changed since signing fir cross city rivals, Arsenal.
A slew of disgruntled Chelsea fans have taken out their anger on Petr Cechundefinedby threatening and calling him all sorts of names on social media.
The 33-year-old has been branded a 'traitor' and a 'snake' while some fans have even gone as far as sending death threats.
Cech however thinks those are not true fans.
"The true fans have sent me messages that are pleasing and positive. True fans will appreciate what I've done and the legacy I've left," Cech said.
"There are some people who have left me negative messages, but they aren't true Chelsea fans."
The fans are not only the ones angry over the goalkeeper's move as Jose Mourinho tried all he could to thwart Cech's move.
Cech however insists his relationship with his former manager has not been broken.
"Jose is one of the best managers in the world, our relationship hasn't changed although he went with Thibaut Courtois last season," Cech said.
"But we respect each other. He made his decision and I made mine. We had a good chat - I know he wanted me to stay but that's the way it goes."
