Here is the Aston Villa manager Martin O'Neill addressing Áras an Uachtaráin, the official residence of the President of Ireland, speaking on the theme 'What it means to be Irish'. This was a lecture conducted in December '08 on the Irish identity to an audience made up largely of young college students as well as President Mary McAleese. The Villa manager discusses amongst other things growing up in a nationalist family, his experiences playing for Northern Ireland and his overall thoughts on his Irish identity. In this fourth part, Martin O'Neill takes more questions and discusses his own contribution to Irish culture, the ability of football to be a unifier and whether he thinks there could be an all-Ireland football team as well as the changes the GAA have made since he played Gaelic games.
