Suarez was pushed out of Barca over the summer as he moved to Atletico Madrid.
Bartomeu, who resigned as president yesterday, said: "The internal restyling of the team had to be done first. I recognise it and I have assumed responsibility by calling the next presidential elections in March.
"We had to rejuvenate the squad and change certain dynamics. This led to the sale of key players, whom I want to thank again today for their contribution.
"We brought young Barça B and talents to the first team for the future."
