French champions PSG suffered the second defeat after seven round of the new season’s Ligue 1 on Friday, losing 2-0 at Toulouse.
This was the first league victory of Toulouse over PSG since 2009.
Yann Bodiger scored from the penalty spot after ex-Toulouse defender Serge Aurier was sent off for a second yellow following a foul on Ola Toivonen in the 48th minute.
Jimmy Durmaz made it 2-0 by beating PSG keeper Alphonse Areola from close range after intercepting a poor Thiago Motta pass 11 minutes from time.
The home side’s goalkeeper Alban Lafont denied Edinson Cavani from point-blank range with a superb save on the half-hour, before parrying the Uruguayan’s header on 41 minutes.
Three minutes later Aurier’s header was cleared from just under the bar by defender Christopher Jullien.
After the defeat away, PSG, who lost just two in the whole of last season, dropped to third in the table with 13 points.
Toulouse, on the other hand, moved level on points with leaders Nice, who are away to struggling Nancy on Sunday, but trail on goal difference.
PSG boss Unai Emery, who took over from Laurent Blanc in the summer, will hope to see an improvement when his side travel to Bulgaria to face Ludogorets Razgrad in the Champions League next Wednesday.
