Guppy followed O'Neill out of Sunderland as incoming manager Paolo Di Canio appointed his own coaching staff. In 2014, he joined O'Neill's coaching staff to specifically coach the wingers and strikers of the Republic of Ireland national side. He helped former teammate Neil Aspin to coach Port Vale during 2018–19 pre-season. O'Neill was sacked by Ireland in November 2018 following relegation out of the UEFA Nations League B Group 3, and Guppy also lost his position. He went on to be reunited with Gary Smith at Nashville SC, where he worked as an assistant coach.
