The man from Dublin's north inner city made a quick hop across the Liffey after last night's 1-0 defeat to spend some time with his family before an early-morning return to his club today, but Hoolahan went back to England with his reputation enhanced by an impressive 45-minute display.
Giovanni Trapattoni described the former Shelbourne man's performance as "fantastic" and said he would be in the squad for the rest of the World Cup campaign, music to Hoolahan's ears.
"It's pleasing to know that Mr Trapattoni has been to watch me twice in the last couple of weeks," Hoolahan said.
"It was a long time since I was last in the squad, four years, so it was good to be back.
"There are a few big games coming but I've just got to keep doing well for my club. The performance may not have been what we wanted but it was just great to get on with these lads.
"The young lads like Robbie Brady and Seamus Coleman were excellent today and the future looks bright for this team.
"I saw those lads in training over the last few days and they looked great."
