 He was involved in Mark Leech's golden goal that won the Setanta Cup for Drogheda in April 2006, but a few months later was released, following a disagreement with manager Paul Doolin, and returned to St Pats.RTÉ reported that "Danger man Fahey was quieter than usual" as Pats lost 2–0 to Hertha BSC in the first round of the 2008–09 UEFA Cup, held at the Olympiastadion; however, in the second leg, despite Pats' "excellent performance" failing to overturn the deficit, an RTÉ feature picked out "Keith Fahey's control of the game, dictating almost every Pat's attack with that delicate but incisive right foot of his.Fahey stood head and shoulders above the many highly decorated full internationals in the Hertha team, showing the full range of his passing from deep and from close range, and generally showing a poise and guile on the ball that you would not expect from a League of Ireland player amongst such illustrious company."
