Chelsea midfielder Jorginho says the dismissal of Thomas Tuchel came as a "surprise", revealing the Blues' players feel partly responsible for his exit.
The German coach was axed last week in the aftermath of a surprise defeat to Dinamo Zagreb in the Champions League, which followed on from Premier League losses against Southampton and Leeds United during an underwhelming start to the season.
Chelsea moved quickly to appoint Graham Potter as Tuchel's successor at Stamford Bridge, with their first game under his guidance coming on Wednesday against Salzburg.
With last week's Premier League action postponed following the death of Queen Elizabeth II, Tuesday's pre-match news conference represented the first opportunity for questions on the managerial change.
Jorginho conceded it is something he has become accustomed to, with Potter the fourth Chelsea boss he has worked under, but says he was caught off guard by the latest switch.
"It's happening a lot, as everyone knows. We're adapting to the new coach, we're very excited to work with him and his staff. It's been quite good the first few days," he said.
"Of course, we had a great time with Thomas, we appreciate everything he did for us, for the club, for the fans, now we have a new challenge to look forward to and we're very excited.
"It was a surprise for everyone. What has been said between the players will stay there, sorry.
"There's always talking around what has happened, but now we have games coming and life is quick, so we don't have much time to stay and think. We need to concentrate on what we need to do."
Jorginho was then asked about Tuchel's repeated criticism of the team in the build-up to his departure, and the midfielder admitted there is work to do.
"It was his feeling, he said that to us as well. We tried to do what we could, we tried to do our best, it's what we do," he added.
"Unfortunately, it wasn't working anymore and the challenge now is to rebuild the confidence because Chelsea are a big club, we have a lot of work to do and to do that we need to work with everyone moving in the same direction.
"Of course, we feel responsible, we were a team, it's not one person who is responsible for what happened, everyone is responsible."
