Cech's sudden departure from the club this week was confirmed with just a short statement.
In announcing Cech had left his role as technical and performance adviser, new Blues chairman Todd Boehly described Cech as an important member of theChelsea family, but there was no mention of his achievements in the position.
The last time he left, he was hailed as an "immense contribution" to the club's success, but he was replaced by Thibaut Courtois as the club's number one.
Monday's exit feels like a big blow. Cech's decision to quit leaves a huge hole for the club's new owners as his influence spread far and wide.
Replacing Cech's football expertise will be a tall order at the beginning of a summer in which they are already starting from behind due to government sanctions.
The triumvirate spearheading decision-making over first-team affairs were formed by Cech and Marina Granovskaia. According to sources, Cech struck up an immediate relationship with Tuchel, helping to convince him to join the club in the middle of the season.
Tuchel has forged a reputation as one of the most engaging, personable, and thoughtful head coaches in the game but Cech was the first point of reference for so many engaging with the Blues. According to sources, Cech was one of the key figures discussing possible fixture rescheduling with the premier league when the division's administrators considered postponements on a club-by- club basis.
Cech was heavily involved when it came to discussing the situation with England when Reece James was called up despite his injury. James left the team. Cech was an important player in the transfer activity. Cech was a prominent figure during talks for many players with one agent describing him as "approachable 24/7."
Sources say that he and his goalkeeping coach were able to identify a possible signing. It is thought that Cech's ability to speak five languages in his native Czech, English, German, Spanish, and French, was a factor in brokering the arrival of Timo Werner.
When fan anger at the proposed European Super League reached a boiling point, Cech left the directors' box to confront the fans head on. There was a similar effect inside. It was Cech who addressed the staff at the training base the morning after the announcement that the club was going to be sold.
Cech gave a talk to the players in Abu Dhabi before the Club World Cup Final against Palmeiras, urging them to seize the moment and capture the last trophy to elude them underAbramovich.
As the new era under Boehly and Clearlake Capital begins, Cech's loss will be particularly felt by Tuchel. Sources close to Cech insist that there was no indication his role would have changed, but it is obvious to all that Boehly is planning to be more hands-on thanAbramovich.
There is some validity to the claim that Cech was keen to keep Romelu Lukaku at the club, but Boehly was adamant that he should be allowed to return to Inter Milan. There will be a confirmation of his return to Inter soon.
Cech said that he was confident of the future success of the club. According to sources, the new regime believes that their expertise in running U.S. sports franchises can be used to run the premier league. It is early days with the takeover, but that is still to be seen.
Should he decide to return to football, Cech'sVersatility will make him an attractive hire for many clubs.
It is not clear what the next move is for the club. Boehly has stepped in as the club's interim sporting director and is playing an active role in what is a vital summer for the club, having lost two of their key players to Barcelona and Real Madrid.
According to sources, MichaelEdwards is Boehly's preferred choice to take on a remodelled role at CHELSEA but they will face competition from multiple clubs for his signature. He wants to take a break from the game.
Other names thought to be under consideration are the former head of recruitment at Spurs, Paul Mitchell, and the ex-Paris Saint-Germain defender.
There isn't a lot of football expertise which is needed by the club. Cech's departure should make people feel more urgent.
