He played his first game in Divizia A on 8 March 1987 in a 2–0 win over FC Brasov. The first two seasons Dinamo finished runners-up, and succeeded to win in the 1989–90 season the title and cup (with Lupu contributing 6 goals and 13 assists in Divizia A); also reaching a Cup Winners' Cup semi-final in 1990.
