PARIS, March 4 (Reuters) - Olympique Marseille will field their B team against arch-rivals Paris St Germain in Sunday's match at the capital's Parc des Princes because of safety fears.
In an interview on the club website, Marseille chairman Pape Diouf said the decision was taken 'because Paris St Germain did not guarantee the security of the OM supporters'.
'We are going to send a team which will include young players and professional players but not players regarded as regulars,' he said.
'We have also asked our supporters not to travel to Paris. I think they understand our position.'
Matches between PSG and OM are always regarded as high-risk and security will be particularly tight after rival groups of PSG supporters fought each other and ransacked a motorway service station on their way back from a match last weekend.
The game, which was due to kick off at 2000 GMT, has been brought forward four hours to help security forces.
The 48,000 spectators will be searched and some 1,200 policemen will be deployed around the stadium whose surroundings will be open only to ticket-holders.
Diouf said earlier that Marseille were considering a boycott of the game.
'PSG are guilty on two accounts; they are refusing to provide 500 tickets we have ordered and have sold them to their own fans who will be seated just above our supporters,' Diouf told sports daily L'Equipe.
'This proximity is potentially explosive. It's sheer madness and incompetence but we are not the puppets of PSG and we could decide not to play.
'That's what we should have done last year when our team bus was attacked by PSG supporters who smashed its windows.'
'Marseille ordered the tickets too late and we sold them to members of our amateur association and to selected people,' PSG security officer Jean-Philippe d'Hallivillee said.
'The two levels of the stand have been secured by a net which makes impossible to throw projectiles on the lower seats.'
PSG chairman Pierre Playau declined to comment.
