Ronan’s move comes after impressive temporary stints at DAC Dunajska Streda in Slovakia and Blackpool in League One last season.
The midfielder has previously made 14 senior appearances for Wolves, most recently in October 2017, and now heads to Switzerland for the next phase of his development.
He’s joined by Dadashov who, in his first season on Wolves books, spent time on loan Pacos de Ferreira and enjoyed a run of games for the under-23s prior to lockdown.
The senior Azerbaijan international scored twice against Tottenham Hotspur in the Premier League 2 in March and will aim to add further goals to his tally in Grasshopper colours during 2020/21.
