The 29-year-old midfielder believes that the Hoops are primed to match the levels of success achieved by former club Dundalk
After surprising many by swapping league champions Dundalk for Tallaght Stadium, Ronan Finn is adamant that the Shamrock Rovers sleeping giant is poised to wake up and justify his decision.
Finn, who spent four years at the Hoops before joining Stephen Kenny's all-conquering side in 2015, has been immediately appointed club captain by manager Stephen Bradley upon his return, and the midfielder feels that Bradley's revamped side can unseat his dominant former club.
"It's a massive club. The potential is here to kick on, win league titles and I want to be part of that," Finn told 98FM.
"Any decision I've made in football I've always taken my time and made sure I've made the right call. I haven't regretted any decision and I don't think I'll regret this one either.
"Dundalk is a great club and there are great people up there. I really enjoyed my time there, it was a great group of lads, but I genuinely feel at this moment that the potential [at Shamrock Rovers] to return this club back to its glory days is here.
The former Sporting Fingal and UCD man won the Premier Division title during his first Hoops spell in 2011, and the 29-year-old wants to see those glory days return after years of underachievement from the Tallaght club.
"I've had success here before and I know how great a place it is when successful. Coming back here, that's what I want to achieve," continued Finn.
"When I signed here first, it was really a special place and that's where the club needs to get back to; winning cups and competing in Europe. It's such a massive club."
Finn is also not shy about admitting that the opportunity to start a part-time career outside football - the midfielder graduated with a business degree from footballing alma mater UCD - provided an extra incentive for his shock switch from Oriel Park.
"It doesn't take a rocket scientist to realise that being a footballer in Ireland doesn't last forever, the wages, the money, it stops as soon as you stop playing. And you've got to be in a position, when you've stopped playing, where you've got something and you're not starting from scratch.
"The potential is there for me to whet my appetite on something [for when I stop playing]."
New manager Bradley, 32, provides a template for Finn to follow in that regard, as does Rovers director of football Stephen McPhail, who expressed excitement about securing the signature of one of Dundalk's key Uefa Europa League performers.
"It's a huge statement from us to bring in Ronan. He's in his prime and the way he's performed in the last year or two especially, it's a massive signing for us," McPhail said.
Finn's arrival marks Rovers' ninth import of the close-season and the second from champions Dundalk - with Darren Meenan also making the move south this winter - as Bradley and McPhail set about restoring the Hoops to the former glories that their latest signing once shared in.
