PARIS (AFP) - Third division Paris FC beat Toulouse, who played in the Champions League qualifiers this season, 2-1 on Sunday to cause the biggest shock of the weekend in French Cup action.

The amateur side, coached by Jean-Guy Wallemme who captained Lens to the 1998 French league title, earned their passage to the next round, joining Lyon, Paris Saint Germain, Marseille, and Auxerre in the last 32.

French first division strugglers Lens, coached by former international striker Jean-Pierre Papin, however slumped to a new low on Friday when they were dumped out by second division Niort.

For Paris FC, victory at first division Toulouse put them on the map.

"This success will get Paris FC talked about more because sometimes we have trouble holding our own alongside PSG," said Wallemme. "The attention this victory has brought is super for everyone at the club."

Toulouse captain Dominique Arribage scored an own goal on six minutes but his side were back in the match just a minute later thanks to a header from midfielder Moussa Sissoko.

Paris FC had to wait till an hour had gone for the winner however when Pape Sarr found the net.

Toulouse had several clear-cut chances but were unable to convert them into goals.

"We had the chance to kill the match in the first half and we were not able to do so," said Toulouse coach Elie Baup. "We payed for that lapse."

Reigning six-times French champions Lyon romped into the next round with a 4-0 away victory against third division Creteil, with Karim Benzema scoring a hat-trick and Juninho getting the other.

Monaco were in debt to 18-year-old substitute Djamel Bakar who hit a hat-trick in the 3-1 win at Brest.

Bakar came off the bench after an hour and levelled in the last minute of normal time before adding two more in extra-time.

On Saturday, French league strugglers Marseille and Paris Saint Germain kick-started the New Year on a winning note.

Marseille beat minnows Beauvais 2-0 to book their ticket while Paris Saint Germain also won 2-0 at Epinal.

It was welcome success for Marseille and PSG, who, although normally among France's most successful clubs, find themselves in the bottom half of the league table.

Ten-time French Cup champions Marseille had little trouble in brushing aside their national division club opponents as first-half goals from Lorik Cana and Djibril Cisse went unanswered.

PSG, who have won the French Cup on seven occasions, thanked first half goals from Clement Chantome and Sylvain Armand for their 2-1 victory over fourth division club Epinal.

"Mission accomplished," said under-fire PSG coach Paul Le Guen.

"It's good because the conditions were a little difficult with a tricky pitch. This could have been a booby-trap for us but we came through it well."

Caen, fourth in the top flight, were knocked out by second division Sedan 3-2.

Alexandre Bonnet, Moussa Sow and Djamel Abdoun were on target for Sedan with Lilian Compan and Yoan Gouffran finding the net for the top flight UEFA Cup hopefuls. It was Caen's first defeat in two months.

On Friday, Lens, third from bottom in the top flight, were undone by a 30th-minute strike from Jean-Francois Riviere in what proved to be the only goal of the game.
