[Dbix-class] Multiple self join problem

I have 2 tables, one for soccer teams and one for players. I want to
find the team having players A, B and C.

Schema::Team has many Schema::Player

How could I accomplish the above? In SQL, one way would be:

select teams.* from teams
inner join players p1 on p1.team = team.id
inner join players p2 on p2.team = team.id
inner join players p3 on p3.team = team.id
where p1.name = 'A'
and p2.name = 'B'
and p3.name = 'C';

How could I do this using DBIx::Class?
