LYON, April 15 (Ligue 1) - Lyon moved to within one win of a record sixth successive Ligue 1 title on Sunday evening courtesy of a narrow victory over relegation-threatened Sedan.
Hatem Ben Arfa notched the only goal of the game a minute before the half-time interval for Les Gones, putting them 17 points clear of second-placed Toulouse, who have six games remaining.
Gerard Houllier's troops can now make absolutely sure of the title by beating Rennes at the Stade Gerland on Wednesday.
The visitors came close to taking a surprise lead in the 12th minute when Nicolas Maurice-Belay's cross was met by the head of Joseph-Desire Job at the near post, but home keeper Gregory Coupet somehow managed to get his fists to the ball and clear the danger.
Lyon responded with a decent chance of their own two minutes later when good build-up play involving Florent Malouda and Kim Kallstrom teed up Sylvain Wiltord, but his low shot was blocked by Sedan stopper Patrick Regnault.
Coupet had to be alert when Job broke through on the counter-attack after 19 minutes, but the Cameroonian's finish was weak.
Morgan Amalfitano then fired in a quick shot looking to catch Coupet unawares, but he dived to his right to make the save.
Job and Amalfitano then combined before the latter tried his luck, only to see it fly narrowly wide.
With the lowly visitors failing to make the most of their chances, Lyon soon showed them how it was done at the other end.
Wiltord provided the pass for Anthony Reveillere, whose cross found Ben Arfa on the penalty spot and his instant volley gave Regnault no chance.
Lyon went in at the break with a one-goal lead and came out for the second half clearly keen to build on their advantage.
Malouda's diving header from Reveillere's cross was just inches off-target in the 56th minute, and Ben Arfa rolled a shot wide six minutes later after seemingly having done all the hard work.
Regnault pulled off the save of the night in the 64th minute to deny Juninho following a well-worked Lyon free-kick, clawing the ball away from the top corner with his right hand.
The last chance of the match also fell to the home side as Tiago looked to lob Regnault in the third minute of injury time, but his effort clipped the crossbar.
