When professionalism was established in 1994 within the Chinese leagues it opened the door for more than one team within each city. This eventually paved the way for the first ever Chinese top-flight city derby, which took place in 2002 when Shanghai Shenhua lost 2–0 to Shanghai Zhongyuan (later renamed Inter) in front of a sold out Hongkou Football Stadium. Known as the Shanghai derby it would be the start of an intense but short rivalry between the two clubs, which reached its peak on the final day of the 2003 league season with both teams within reach of winning the league title. Shenhua won their game while Inter surprisingly lost theirs to relegation fighting club Tianjin Kangshifu. This saw critics dispute the title win and it was eventually discovered that both teams had players and officials match-fix games throughout the campaign. Shenhua would retrospectively lose their title while the Inter owners decided it was financially unviable to remain in Shanghai and relocated their team to Xi'an, which effectively ended the rivalry.
