for the first time in a qualifier for UEFA Euro 1984 against Denmark. It served as the primary home ground for the team for the rest of the 1980s and the 1990s, until 2001 when it was closed for renovations. Meanwhile, a large number of matches were held in various stadiums including old choices and some new in provincial cities all over the country, something that did not change until the early 2000s, when the Athens Olympic Stadium was almost abandoned. From the start of the 2000 until the qualifiers games of Euro 2004, the Greek National Team uses Leoforos Stadium as its home.
