Ireland exited UEFA Euro 2012 at the group stage, after losing to eventual finalists Spain and Italy. Early in 2014 FIFA World Cup qualification, Ireland suffered a 6–1 defeat to Germany at home with a severely depleted team available. On 29 May 2013, Trapattoni's Ireland side faced off against England for the first time in eighteen years at the Wembley Stadium in a match which ended 1–1. Trapattoni parted ways with the Republic of Ireland national team on 11 September 2013 by mutual consent, after a defeat by Austria effectively ended their chances of qualification for the 2014 World Cup.
Although Trapattoni was known for his defensive minded approach as a manager, his teams often made use of a ball–playing sweeper or libero – with good technique, vision, and an ability to read the game –, who was responsible both for defending and starting attacking plays from the back, as well as a creative and skilful offensive playmaker in midfield behind the forwards. As such, his teams were known for their defensive strength and playing style, as well as their ability to score from counter-attacks. In 2014, Trapattoni attributed his success and tactical intelligence as a manager to his time playing in midfield throughout his playing career, which allowed him to understand both the offensive and defensive phases of the game. Throughout his career, he used several different formations, including a 4–4–2, a 4–3–1–2, 4–2–3–1, 3–4–1–2, and a 3–5–2, as well as his fluid zona mista system; the latter system made use of a sweeper, a man-marking centre-back – or stopper –, two full-backs, a defensive midfielder, a regista or attacking midfielder, a second striker, and two wingers behind a lone striker or centre-forward, although players would often switch positions in this system, with only the stopper having a fixed role.
