Roberto di Matteo insists he had a good relationship with former Chelsea manager Andre Villas-Boas.
Di Matteo takes charge tonight for their FA Cup replay against Birmingham City.
He told chelseafc.com: "It has been a very difficult 24 hours for a lot of people at the football club.
"Andre has brought some very good, positive ideas and changes to this football club and we will benefit from his changes. I enjoyed very much working with him and we will remain friends for the rest of our lives, but I will have to move on for this club and try my best with the players we have here."
