PARIS, Oct 5 (Reuters) - Mickael Pagis scored a hat-trick as Stade Rennes handed Olympique Lyon their first Ligue 1 defeat of the season with a 3-0 thrashing of the seven-times champions on Sunday.
Striker Pagis found the back of the net once in the first half and twice after the interval, making up for his side's UEFA Cup exit against Dutch side Twente earlier this week.
Lyon, who started with Brazilian playmaker Juninho on the bench, barely threatened the Brittany side but remain top of the standings with 19 points from eight matches, two above Toulouse, 1-0 winners over Auxerre on Saturday.
Olympique Marseille, who beat Caen 2-1 on Saturday, are three points adrift of Lyon with Rennes up to seventh on 13 points.
Five days after snatching a 1-1 draw at Bayern Munich in the Champions League, Claude Puel's side were nowhere to be seen at the Stade de la Route de Lorient.
Puel's decision to field Swede Kim Kallstrom as a left back cost Lyon their first goal as Moussa Sow stormed up the right flank before providing Pagis with a perfect pass that allowed the former Marseille striker to open the scoring on 17 minutes.
The second goal came from the other side of the pitch with Olivier Thomert feeding Pagis with another fine cutback 11 minutes into the second half.
Pagis did it all on his own for the third, a superb 25-metre volley that went into the top corner of Hugo Lloris's goal.
Paris St Germain, who had lost their last two league matches, managed a 1-1 draw at Nancy despite being without midfielders Claude Makelele, Ludovic Giuly and Jerome Rothen, all injured.
They went ahead in the opening five minutes when Guillaume Hoarau headed home after connecting with a Stephane Sessegnon cross.
However, Paul Le Guen's side struggled and Nancy defender Damian Macaluso levelled with a powerful header from a Benjamin Gavanon free kick.
Nancy and PSG remain in the bottom half of the table, in 15th and 11th place respectively.
Elsewhere, Bafetimbi Gomis and Geoffrey Dernis scored either side of the interval to give St Etienne a 2-0 victory over Monaco, who have now lost their last three league games.
