Overview
- Colorado confirmed the transfer after Ronan spent three-and-a-half seasons with the Rapids and the clubs completed terms for a two-year deal with an option for a third season.
- Aberdeen framed the signing as a reunion with Stephen Robinson and said Ronan will provide creative experience, work rate and midfield depth learned during his time at St Mirren and in MLS.
- Colorado president Padraig Smith publicly thanked Ronan for his service, and the club can now use the freed roster place and open U22 slot to give minutes to younger midfielders such as Josh Atencio and Wayne Frederick II.
- Reports did not disclose an official fee; local coverage speculated the sum was modest (roughly $500,000) while public valuation services list a higher market value near €1.4 million.
- Ronan made roughly 103 appearances for Colorado across 2023–26 with limited goal totals and intermittent injuries, and Aberdeen described the move as part of its push to strengthen the squad as it aims for top‑table finishes and a return to European competition.
