"Each week our supporters tweet some great pictures from matches and, after seeing how good they are, we thought we would set up a competition to reward the best ones," said Premiership Rugby Communications Director, Paul Morgan.
"Aviva Premiership Rugby fans are some of the friendliest and most passionate in the world and we want to capture their emotions in print. This competition is about us showing off some of the greatest supporters in the world."
