Barcelona have reportedly placed 12 first-team players on the transfer list this summer as they look to raise funds for potential new signings.
The report claims that midfielders Arturo Vidal, Carles Alena, Rafinha and Ivan Rakitic are also surplus to requirements, in addition to attackers Ousmane Dembele, Martin Braithwaite and Philippe Coutinho.
Todibo, Alena, Rafinha and Coutinho have all spent at least part of the 2019-20 campaign away from the club on loan, and the latter will be with Bayern Munich until their Champions League challenge has finished.
Semedo is currently being linked with a high-profile move to Manchester City, while Dembele could also move for big money this summer despite his injury problems.
Barca, who conceded the 2019-20 La Liga title to Real Madrid, will face Napoli on August 8 in the second leg of their last-16 clash in the Champions League, with the tie level at 1-1 from the first leg in Italy.
