"All our players are looking forward to the match and we are ready for the challenge ahead. We are looking forward to hosting the Muratti Final after all the hassle everyone has been through over the past few years. It’s great for the Channel Island football community to come and enjoy the biggest game of the season.
Guernsey have most of their players playing in Step 4, therefore if we can win again it will be another great achievement for us. We have a chance to make it four from the last five finals and we will do everything to make that happen." - Martin Cassidy.
