Twickenham will host it's first Heineken Cup quarter final on Saturday the 6th of April and will be between Saracens and Ulster Rugby.

Saracens earned a home tie by virtue of winning a highly-competitive Pool 1 and have moved the match from their new home in Barnet to Twickenham.

Saracens opposition team Ulster who topped Pool 4 will be aiming to go one better this time after losing to Leinster Rugby in the 2012 final at Twickenham.

Although the home of English rugby has staged eight Heineken Cup fixtures to date, including four finals, the clash of the innovative English club and last season's finalists will be a new departure in Twickenham's illustrious history.

With strong interest expected in the tie, the record attendance for a UK Heineken Cup quarter-final of 37,881 set at Murrayfield last season when Edinburgh Rugby defeated Toulouse, could be a target.
