Houllier has led Lyon to their last two triumphs

Gerard Houllier's team are now 17 points clear of second-placed Lens, who took second spot in the table following their 2-0 victory over Le Mans.

It is the first time a club has achieved this feat in the league since the competition started back in 1932.

Jacques Santini won the first before Paul Le Guen led Lyon to the next three, and Houllier for five and six.

Lyon made up for their disappointment in the Champions League by becoming the first side from any of the so-called five major leagues (England, France, Germany, Italy and Spain) to win six straight titles.

"Maybe we didn't reach all our objectives this season but this sixth title is historic," said Houllier on French station RTL.

But the Frenchman admitted he will be seeking assurances from the club ahead of next season.

If not everyone's happy, I'll go somewhere else Gerard Houllier

"So many things have been written and said, even this week, that I have asked myself some questions, not regarding my future, because I know what I'm going to do," he said.

"However, there are a certain number of guarantees that I would like to have and have not yet had.

"One day it's with my staff, the next it's with certain players, who come to me to offer me assurances, then it's the club bosses.

"It's been a more difficult season because we haven't achieved all our aims but you can't say it's been a bad season.

"In two years there have been 76 championship matches and the club has been top for 70 of them, given that we will remain top for the six that remain.

"That's not bad. But if it's not enough, I can understand. If not everyone's happy, I'll go somewhere else."

Houllier was at pains to point out he had no problem with Lyon president Jean-Michel Aulas, although he called on the club chief to clarify his future.

"I get on very well with the president. He's a very good president. Maybe he's not given the credit he deserves because he provokes and bothers others.

"For a coach, he's a great president because he supports you. But it's normal that I have some doubts given the media bombardment that comes my way."

Aulas described Houllier as "irreplaceable" and promised him a budget of �120-135m (180-200m euros).

St Etienne and Marseille held the previous record of four consecutive league titles.

St Etienne were winners from 1967 to 1970 while Marseille were champions from 1989 to 1992.

In 1993, Marseille ended the season top of Ligue 1 for the fifth consecutive year but were stripped of that title for match-fixing.
