But the city's major, Ivo Opstelten, said celebrations would be toned down for the match between Rotterdam-based Feyenoord and newly-crowned Bundesliga champion Borussia Dortmund.

"The match will take place and it will take place in all sobriety," said Opstelten.

If Feyenoord win Opstelten has agreed with the chief of police and the public prosecutor that any post-game event would be moved away from the city hall if Feyenoord win.

On Tuesday thousands of people laid flowers, notes and gifts - and lined up for hours to write messages of condolences outside the city hall as tributes poured in for Fortuyn.

And in the event of a victory for the German team Opstelten said: "Borussia will go straight back to Dortmund after brief celebrations in the stadium."

Shocked

Dortmund coach Matthias Sammer said before his team's training session Tuesday his team was shocked by the shooting.

"The tragedy is not in our immediate surroundings but when things like that happen, you can't help it but start thinking what went wrong," said the Dortmund coach.

While Feyenoord coach Bert van Marwijk said: "I cannot put into words what happened - but we have to look forward to the match.

"It's extremely difficult to put a team in the right mood under these conditions. It was an extreme shock when I heard what happened."

Uefa had quickly denied suggestions the game may be postponed because of security fears after Fortuyn, known for his far-right, anti-Muslim views, was shot in Hilversum, near Amsterdam.

A spokesman said: "We have checked with security officials and as far as we are concerned the game will definitely go ahead.

"Planning for the game has been going on for several months and Monday's events should not change them at all."

Dutch police plan to segregate rival Feyenoord and Borussia fans in the bustling port city before, during and after the game.

Around 40,000 fans are expected to pack into the Feyenoord stadium for the biggest game the city has hosted since the Euro 2000 final.

German and Dutch fans will be channelled into two separate parts of the city amid stringent security for the game.
