Shane Patrick Michael Duffy (born 1 January 1992) is an Irish footballer. Duffy plays for English Premier League club Everton. He has chosen to represent Republic of Ireland at senior international level despite having represented Northern Ireland at junior level. This decision was a catalyst in the IFA's decision to take a case to the Court of Arbitration for Sport to prevent players switching allegiance from Northern Ireland to the Republic of Ireland. The case failed, with the court ruling that as Northern Ireland-born people are entitled to Irish citizenship by birth, they are entitled to play for either the Republic or Northern Ireland.
