lost the final with 0–2 from HFC Haarlem. In this period Vitesse had top players, likes Willem Hesselink and Just Göbel. These players were also active in the Netherlands national team. In 1914 John William Sutcliffe became the first foreign trainer. During World War II, Vitesse did not play-official matches because playing football in the open air was forbidden. During the Battle of Arnhem, the residents of the city were forcibly evicted from their homes, allowing the Germans to turn the north bank of the Rhine into a heavily defended line. Residents were not allowed to return home without a permit and most did not return until after the war. The football field and clubhouse was completely destroyed. The damage was repaired in the years after the liberation. In 1984 it was decided to divide the professional and amateur sections of the club. The professional section was renamed SBV (Stichting Betaald Voetbal – "Professional Football Foundation") Vitesse whilst the amateur section became "Vitesse 1892", which lasted until they disbanded in 2009. From 1984, Karel Aalbers was the president of SBV Vitesse. Aalbers' goal was to bring Vitesse from the bottom of the Second League (Eerste divisie, now Jupiler League), the league in which the club originated, to the top 40 soccer clubs of Europe. He developed the basic idea for the 'Gelredome', a stadium with a sliding pitch that can be moved out of the building. Later, the same system was applied in Gelsenkirchen (Schalke 04) and in Japan. Events such as pop concerts can be held without damaging the grass. Gelredome opened in 1998. It has a roof that can be opened and closed. It is fully climate controlled as well. In the first season after the opening, Gelredome's attendance rose to 20,000, (from less than 8,000 in the old stadium). Vitesse made their debut in European competition in 1990. The club won their first match in the first round 1–0 over Derry City. The club remained financially sound through making notable profits on the transfer market. Players such as Roy Makaay, Sander Westerveld, Nikos Machlas, Glenn Helder and Philip Cocu were sold for large sums of money. Others came to occupy empty player positions, such as Mahamadou Diarra and Pierre van Hooijdonk. Vitesse finished in top 4 positions, made profits and showed a solid balance sheet in the final years of Aalbers' presidency. Also, the club became regular
