The Blues have also strengthened their coaching set up.
"Last season saw us blood a number of young players and twenty matches were won or lost by less than one score.
"With that in mind one of the main areas we wanted to develop was the technical skills in attack and defence as well as the set piece, especially the scrum.
"We aim to bolster the coaching team with the appointment of Dale McIntosh, Andi Kyriacou, Mark Ring who will be involved on specific times throughout the week with player skill development."
