Entity Framework JOIN usage

The objective: write a query that selects all Leagues that a given user has access to. 

The standard SQL query for a JOIN and a WHERE clause on the table you joined. 
  
    SELECT *
    FROM League
    OUTER JOIN LeagueUser ON LeagueUser.League_Id = League.Id
    WHERE LeagueUser.User_Id = [passed id]

And the proposed EF query.

    List<League> myLeagues = _db.Leagues.Join(_db.LeagueUsers,
      league => league.Id,
      leagueuser => leagueuser.League.Id,
      (league, leagueuser) => leagueuser)
      .Where(leagueuser => leagueuser.User.Id == user.Id)
      .ToList();
	
The query correctly returns the leagueuser, which is not the corret return that I need. I need to return league, but am just not sure how. 

League.cs

	public class League
	{
		[Key]
		public int Id { get; set; }
		public string Name { get; set; }
		public int RegisteredByUserId { get; set; }
		public bool ActiveStatus { get; set; }
		public virtual ApplicationUser RegisterdByUser { get; set; }
	}

LeagueUser.cs

	public class LeagueUser
	{
		[Key]
		public int Id { get; set; }
		public virtual League League { get; set; }
		public virtual ApplicationUser User { get; set; }
		public UserStatus UserStatus { get; set; }
	}
