On 16 August 2016, during Steaua's Champions League play-off 0–5 loss to Manchester City, undercover Dinamo fans displayed a huge message saying Doar Dinamo București ("Only Dinamo Bucharest"), which was labelled one of the biggest pranks in football history. Between October 1991 and April 2000, Steaua counted 19 undefeated official matches in front of their rivals, both in the championship and the cup. Just as well, a period of 17 years and 7 months has been recorded in which Dinamo did not manage to win away against Steaua in the domestic league. The second-most important rivalry was with Rapid București, often called Bucharest derby. Several matches throughout the years between Steaua and Rapid have also ended in serious clashes between fans. The conflict has become even fiercer after Steaua outpassed Rapid in an all-Romanian quarter-final of the 2005–06 UEFA Cup. The local sports newspapers said that the two teams were linked up in this quarter-final by the line of the number 41 tram which links the Ghencea Stadium to the Valentin Stănescu Stadium. Milder and historical rivalries are also with non-Bucharest-based teams, such as CFR Cluj, Universitatea Craiova, Politehnica Timișoara, Petrolul Ploiești, Universitatea Cluj and a recent one with Astra Giurgiu. Friendships As Steaua is the most popular club in Romania, there are, besides Bucharest, several cities counting a great majority of red and blue supporters among football lovers. Widely speaking, these cities are predominant in the Eastern half of the country, particularly in the regions of Moldavia, Greater Wallachia and Northern Dobruja. Cities such as Suceava, Piatra Neamț, Bacău, Galați (inside Moldavia), Constanța (Northern Dobruja), Buzău, Brăila, Târgoviște, Călărași (Greater Wallachia), Râmnicu Vâlcea, Târgu Jiu (Oltenia), Brașov, Oradea, Sibiu, Târgu Mureș or Petroșani (Transylvania) enjoy a great majority of Steaua fans which are often well-received even by fans of the local teams. The club is also popular outside the borders, notably between Romanian emigrants. The Valencian Community in Spain accounts for an important number of supporters, being the most important area for this matter. Steaua fans are also maintaining good relations with the fans of CSKA Sofia of Bulgaria, with whom they share the common root of once representing the teams of their national armies. Some ultras are also friends with the ultras from UTA Arad, Corvinul Hunedoara and Farul Constanța.
