Goalkeeper Aaron Dillon insists it is a 'dream come true' to sign his first professional contract with the club.
The 20-year-old Irishman has put pen-to-paper on a one-year deal with the option of a further 12 months.
"It is amazing really, I never thought it would happen," he said. "It is a dream come true.
"It isn't easy coming from Ireland to do this, it has been a lot of hard work for the last two-and-a-half years, but I'm happy it is finally done."
The former Galway United stopper moved to England from Ireland two years ago and has spent the past two seasons training with the likes of Liverpool and Crewe Alexandra as he attempted to land his big break.
He was invited by Rovers' goalkeeping coach Ben Benson to link up with the development squad in pre-season and is now delighted that his trial spell with the club has led to a permanent stay.
"I played in Galway in Ireland for a few games last season, but it was about two years ago when I first came over," he added.
"I went to Crewe for a season and a half, training with them. Then in October last year a goalie coach from Liverpool came down and asked if I could train for a day and I stayed there until the end of last season.
"Training with them was a massive step up. At first I thought I'd be out of my depth, but I think I did well. It was a great boost and a great help for me to train there. I think without Liverpool I would have struggled to get in here.
"I then got a call to come on trial here and I've been here since the start of pre-season, so I think I've done well.
"It is an amazing feeling. It is a massive opportunity and a massive club to be a part of.
"The real hard work starts now. I'm excited to get going and to show everyone what I can do.
"It has been a while since I played, so I'm looking forward to getting back to playing competitive football again and hopefully we can do good things this season."
