Furious Manly chairman Scott Penn says it is an "absolute disgrace" that they were not permitted a home final against Penrith, saying they deserved to have been playing before a parochial crowd as the Melbourne Storm and Sydney Roosters did in securing narrow wins on the weekend.

The Sea Eagles were gutted by their elimination from the competition, with a controversial try awarded to Panthers centre Tyrone Peachey breaking a 10-10 deadlock with six minutes remaining on Saturday night before Penrith scored again at the death to prevail 22-10.

The game was staged before an underwhelming crowd of 15,408 at Allianz Stadium, where Manly were forced to play under the NRL's semi-finals stadiums policy. Penn believes that in having to travel away from the northern beaches they were stripped of an advantage afforded to other "home" teams in the finals.

The club's majority owner plans to convey his displeasure to the NRL on Monday, arguing that clubs such as Manly and Cronulla should be able to host finals at their regular home grounds in the first week of the semi-finals "at the very least". The Sharks were also technically the home team against North Queensland at Allianz on Sunday, a match that drew another modest attendance.
