Just 16 months after guiding the Blues to Champions League glory, Tuchel was shown the exit by new owner Todd Boehly after losing their Champions League group stage opener to Dinamo Zagreb on Tuesday.
The shocking news continued a tradition of merciless dismissals which emanated during the Roman Abramovich era and shows no sign of slowing down.
Former Manchester United defender Rio Ferdinand, disagreed with the decision, telling his FIVE YouTube channel: "Anybody who comes in now, you would think it is a downgrade on Tuchel and his resume.
"He is a proper manager. All the players I speak to talk positively about him. He is honest and direct. He has clarity on how he wants to play.
"I can't understand it. It doesn't make sense to me.
"Tuchel has a 60 per cent win rate. A lot of managers would be delighted to have that.
"Chelsea have set their stall out now and said, 'This is us now'. It's a giant statement from Todd Boehly and his new regime. It leads you to the point, where will they go?"
Jamie Carragher, agreed with his former England teammate, telling Sky Sports: "It's a shock because I just thought the new regime at Chelsea would be different to Roman Abramovich."
"If Abramovich was still in charge, you'd fear for Tuchel because of what happened in the past with Jose Mourinho, Antonio Conte, Carlo Ancelotti – lots of great managers.
"But I did feel as if it might have been a different type of regime, so it's a huge shock. It hasn't been a great start, we get that.
"But Chelsea felt like a team who needed the transfer window to end, get the squad they wanted and give a top-quality manager a chance over the next few weeks or months.
"We're talking six games into a season. He bought Pierre-Emerick Aubameyang who made his debut last night and Wesley Fofana's played two games.
"The idea that this team's been put together with a lot of money spent – I understand that – pressure comes with that and Thomas Tuchel will understand that.
"But he was almost like a director of football a lot through the summer as well, he was heavily involved in bringing the players in.
"So, he should have been given more time certainly, even just the next three games which takes them up to the international break, I don't know what the rush was right now."
Manchester United boss Erik Ten Hag added: "I feel sorry, but there is nothing I can say. It's Chelsea, not Man United. It's early in the season, yes."
