Connect three tables?

Hi! How can I make a select of three tables? 1st table: fixtures with league_id 2nd table: leagues with countries_id 3rd table: country

Now I want to select fixtures with league und and with country. But I can't get the country.

        $fixtureDB = new \App\Fixture();
        $fixtures = $fixtureDB
            ->with('league')
            ->with('country')

And the model fixture with:

    public function league()
    {
        return $this->belongsTo('App\League');
    }
    public function country()
    {
        return $this->hasManyThrough('App\Country', 'App\League');
    }

Where is my mistake?
