Olivier Giroud expects everyone to have a clean slate at Chelsea under the new manager.
Derby boss Frank Lampard has agreed terms to return to the Blues.
"Last year there were ups and downs but the main thing for me was to always show myself determined," he told L'Equipe.
"I'm happy with my season.
"A European cup after the World Cup is something extraordinary. I feel good here. Now another coach will arrive and the hierarchies will be reset. We have lost our best player but I do not worry."
