Diego Simeone says a disciplinary issue with Atletico Madrid striker Diego Costa has been settled.
Costa reportedly refused to train on Thursday over a club disciplinary process following his red card against Barcelona.
An outburst at the referee against LaLiga's leader earlier this month saw Costa sent off, then hit with an eight-match ban.
Atletico's slim LaLiga title hopes were effectively ended as a result, but Simeone continued to defend the striker ahead of Saturday's trip to Eibar.
"What I can tell you is it's an internal situation, that we solved it yesterday and today Diego was training as he has always trained," Simeone told a news conference on Friday.
"I have explained several times. I do not change what I think about Diego. I think he did not have a good season, marked by injuries. And I have no doubt that next season, all the rebellion and all the players who is in all situations that have lived this season, will do very well.
"This season he has not been able to have continuity. Then the expulsion moves him away from the competition from here to the end and all this will make him rebel. Costa will have a hunger and desire to reverse this situation that he has lived this season.
"Players today cannot take anything for granted in the future. Always the players can have the opportunity to leave. We always want to compete with the best and those that we consider that can make the team good and keep it growing."
Asked again about Costa's punishment over the ban, Simeone added: "I was clear at the start. It is an internal issue and has been resolved internally and is now resolved.
"It is an internal issue and we resolve it internally. In the family when situations happen they are resolved without telling anyone on the street."
Atleti can boost its chances of finishing second, above city rival Real Madrid, by winning away to Eibar on Saturday.
"It will be a hard game like all against Eibar," Simeone said. "They are the one who presses in the best way among the rivals in Spanish football.
"Drowning the exit and trying to make mistakes. We know about their characteristics and will try especially at home to do it in the best way."
Diego Godin and Thomas Lemar are available after being given medical discharge from thigh and hamstring injuries respectively.
