Spanish media said the former Chelsea forward didn't practice because he was unhappy with a lack of support from the club after being suspended for eight matches for insulting a referee. Costa will not play again this season because of the ban he received for the incident in a league match against Barcelona two weeks ago.
Simeone says he expects Costa, who has been below his best during an injury-hit campaign, to be extra motivated next season. Atletico is nine points behind leader Barcelona with six matches remaining. It visits Eibar on Saturday, while Barcelona hosts Real Sociedad.
