postgresql - How to get all datasets that match a condition. NOT OUTTER JOIN

I want to get all teams that contain a certain dataset of mitglieder AND all other mitglieder's datasets in those teams. For Example:

Team A got Anna and Peter mitglieder, Team B got Anna, Maria and Johnny and Team C got Johnny and Mia. If I want to find Anna then the output should look like this:

enter image description here COUNT isn't important right now.

I tried this code, but this code gives me all datasets of mitglieder.

select teams.name, mitglieder.username, count(eintraege.eintrag_id) 
from (eintraege 
inner join teams 
    on eintraege.team = teams.team_id) 
right join mitglieder 
    on eintraege.mitglied = mitglieder.mitglied_id and mitglieder.mitglied_id = 101 
group by teams.name, mitglieder.username;

Thanks in advance!!

Hi i think this is your answer

select teams.name, mitglieder.username, count(eintrag_id) 
FROM eintraege 
LEFT JOIN teams on eintraege.team = teams.team_id 
LEFT JOIN mitglieder on eintraege.mitglied =mitglieder.mitglied_id 
where teams.team_id in (SELECT team from eintraege where mitglied = 1)
group by name, mitglied_id
order by teams.name

working example http://sqlfiddle.com/#!9/3956db/3
