The teams were deadlocked at 1-1 after 90 minutes in the season's traditional curtain-raiser between the champions and cup winners from last season.

The shoot-out went right to the wire until PSG's Ivory Coast striker Bonaventure Kalou saw his spot-kick saved by Lyon reserve goalkeeper Remy Vercoutre, before Lyon's Mali international midfielder Mahamadou Diarra sealed the victory with a successful strike from 12 yards (11 metres).

Lyon's victory was all the more impressive as they were missing nine World Cup players who are still recovering from the finals.

The team's second string also had to battle searing temperatures and the loss of the first goal of the game.

"It was hot and you have to congratulate the two teams who produced a good match," said Lyon coach Gerard Houllier.

"Not everything was perfect but if that was the case from the first match (of this season), that would be worrying. It will come."

Jerome Rothen fired PSG ahead after Vercoutre had palmed away a Pierre-Alain Frau header from six yards, just passed the hour mark.

But Lyon were level from the spot just nine minutes later as Karim Benzema scored after Sylvain Armand was penalised for pushing new Swedish signing Kim Kallstrom in the box.

"Honestly I think my team deserved more," said disgruntled PSG coach Guy Lacombe. "It's infuriating to lose like this: Lyon succeeded through penalties, thanks to the (home) crowd.

"But at least I can hold onto the content of the match, during which PSG deserved to win."
