Think he traveled to Germany in 1988 supporting England. Made his debut for Ireland a year later. Wasn't long seeing off likes of Liam Brady and Ronnie Whelan in the Irish team. Jack Charlton spotted his potential. When the likes of Carlton Palmer and Batty were in England's Euro 92 squad, it's fair to say Englands loss was Ireland's gain.
Very good player for Villa and Ireland. Better athlete than Barry or McGinn perhaps. Definitely not one to shy away from a 50/50 either.
