Team of the Season
The 2021–22 Allianz Premier 15s Team of the Season, which was revealed on 29 June, features players from seven different clubs and three different nationalities. The team was selected by a panel of five media experts–Jessica Hayden, Nick Heath, Kat Merchant, Sara Orchard and Fiona Thomas.

Allianz Cup
The Allianz Cup saw the Premier 15s clubs ranked by their previous finishing position and drawn in two pools of five, with clubs playing each other once in two home games, two away games, one bye week over five rounds.

The top two teams in each pool will progress to the semi-finals played at the highest ranked clubs’ venues (16 April 2022) as well a third-placed play-off and final (both 22 April 2022). The Allianz Cup final will be played at the home venue of the winning semi-finalist club with the highest points’ difference.

The bottom four ranked teams will enter fifth, seventh and ninth placed play-off finals with the home team once again determined by stage one league tables. The Cup competition also gives greater exposure to every Allianz Premier 15s round.
