Have you read through the documentation? It's outlined clearly there.

<?php

class Player extends Eloquent
{
	public function rank()
	{
		return $this->hasOne('Rank');
	}
}

class Rank extends Eloquent
{
	public function player()
	{
		return $this->belongsTo('Player');
	}
}

Thanks for suggestion @crhayes, I have made a edit in question, that not all players are ranked I should have made it clear first hand only sorry.

If not all the players are ranked then the ones that dont have a rank, the relationship should not return anything... You can check for this.

You can do one of two things:

// Get all of the ranks with the associated player
$ranks = Rank::with('player')->get();

// Get all players that have a rank
$players = Player::has('rank')->get();
