Twickenham will host the Heineken Cup final next year for the first time since 2000 when Northampton beat Munster 9-8.
A then record 68,441 watched that match and the organisers would be very happy with a repeat on Sunday, May 23.
European Rugby Cup chief executive Derek McGrath said: “From today all roads lead to Twickenham.
“Announcing the venue now is in the best interests of the Heineken Cup as it adds focus, value and incentive to the tournament and all its stake holders and partners.”
Tickets for the 2004 final will go on sale tomorrow.
