saddled with millions of debt and came close to bankruptcy. Despite the financial situation, Groningen recorded their highest-ever league finish in 1990–91—third place. Managed by Hans Westerhof, Groningen competed for the league title with Ajax and PSV until the last part of the season, when suspensions and injuries to first team players saw them drop points. Groningen's forward duo, Hennie Meijer and Milko Djurovski, had 27 goals between them; Meijer was named Dutch Footballer of the Year after the season ended. Decline, recovery and a new stadium (1991–2010) Although Groningen recorded a 5th-place finish in 1991–92 and qualified for the 1992–93 UEFA Cup, the team began to slide down the league table; they were eventually relegated to the Eerste Divisie in 1997–98. During this period, Groningen had little financial resources left and made many managerial changes in a search for success. The side returned to the Eredivisie in 1999–2000 following a first-place finish in the promotion play-offs group. During the season, Groningen set several club records: they scored 81 goals, won 10 matches in a row and recorded their largest victory—10–1 against DVS '33 in the KNVB Cup. In December 2000, 16-year-old Arjen Robben made his professional debut under coach Jan van Dijk; Robben was soon sold to PSV for a fee of 3.9 million euros. Groningen avoided relegation in their first seasons back in the Eredivisie; under coach Ron Jans, appointed in 2002, Groningen began to return into the top half of the Eredivisie. In January 2006, Groningen moved from the outdated Oosterparkstadion—the club's first home stadium—to the newly built Euroborg. The club's average home attendance increased from about 12,000 in the Oosterparkstadion to around 20,000 in its new stadium. The team went the first 15 league games unbeaten at Euroborg, and the stadium was soon nicknamed "De Groene Hel" ("The Green Hell"). At the end of the 2005–06 season, Groningen finished in fifth place and qualified for the play-offs which determined a place in the preliminary round of the UEFA Champions League. Groningen reached the final but lost against Ajax on aggregate in the last minutes of the second leg; the team qualified instead for the 2006–07 UEFA Cup in which they were eliminated by Partizan Belgrade in the preliminary round. Groningen again qualified for the UEFA Cup preliminary round the following season but were eliminated by Italian side Fiorentina after a penalty shootout. In 2009, Groningen sold
