Supporters can 'tweet or message in' questions for coaches and captains of their sides or opposing teams in this year's competition.
We will then put a selection of the best questions to the players and coaches and feedback the answers on the day.
We will be tweeting behind the scenes photographs, uploading quick-fire interviews and bringing you the latest news.
