Thanks Rory,
This query solves the problem:
SELECT client.client_name, IFNULL( COUNT( sales.sale_id ) , 0 ) AS total
FROM CLIENT LEFT JOIN sales ON client.client_id = sales.client_id
GROUP BY client.client_name
ORDER BY total DESC
Also thanks to Nandar and Prabhu, but MySQL does not recognize

| 1 | John|
| 2 | Mark|
| 3 | Luke|
| 4 | Matthew |
