The Roman Abramovich era has come and gone, and Chelsea are in a period of transition.

A change of ownership back in May saw American businessman Todd Boehly lead a consortium which bought the Premier League giants from Roman Abramovich.

Chelsea endured a tumultuous period towards the end of last season, as the club was hit with sanctions.

Chelsea boss Thomas Tuchel has spoken about the transition period, and insists he is happy with the transfer business done this summer by the Todd Boehly.

Tuchel also admits that he is missing the calming presence of club legend Petr Cech.

“I still think we are in transition with a new ownership,” Tuchel told Soccer AM when asked to sum up Chelsea’s eventful pre-season.

“Petr Cech who was also such a big key factor, also for me in the season in the building here in Cobham, speaking with everybody and the staff and being a huge support for me.

“He’s not here any more so there are some changes. We are positive but we are a bit in transition so we are excited but it comes pretty early (the season).”

Tuchel also revealed he found it impossible to switch off during the summer break, with so many issues to be sorted out, particularly related to player recruitment.

He said: “Normally I switch off, I train myself to switch off but this season it was impossible. New ownership, new communication, transfer period.

“We lost key players. It was not a summer like the last years and it felt a lot shorter than it actually was.”
