At her third Olympic Games in Seoul 1988, she finished a disappointing ninth in the 1500 m final won by her team-mate Paula Ivan. In 1989, she defended her 1500 m World Indoor title in Budapest, winning in a championship record of 4:04.79. In February 1990, she broke the world indoor mile record with 4:17.14 in East Rutherford. The record stood for 26 years until Genzebe Dibaba ran 4:13.31 in 2016. A month later, she won her third European Indoor title over 1500 m in Glasgow. A medal favourite for the 1990 European Championships in Split, she could only finish sixth in the 1500 m final. In 1991, she was fourth in the 1500 m finals at both the World Indoor Championships in Seville and the World Championships in Tokyo.
