Ioan Sabău, nicknamed Moțul after the people from Țara Moților because of his ambition, was born on 12 February 1968 in Câmpia Turzii, starting to play football at junior level in 1985 at Universitatea Cluj, under the guidance of coaches Alexa Uifăleanu and Nicolae Szoboszlay. He made his professional debut playing for Universitatea in the 1984–85 Divizia B season under coach Remus Vlad, helping the team win promotion to Divizia A, where in the following season he made his debut on 8 March 1986 in a 1–0 loss against Rapid București, also under the guidance of coach Remus Vlad. In 1988, Sabău had offers from Dinamo București and Steaua București, choosing to play for the first because of coach Mircea Lucescu's project of building a team composed of mainly young players like himself. But Steaua's officials with president Ion Alecsandrescu and the relatives of dictator Nicolae Ceaușescu, his son Valentin who was Steaua's unofficial president and brother Ilie who was a Romanian army general insisted and pressured Sabău on several occasions to sign with the club, especially during his military service in which he played for Ministry of National Defence club and friend team of Steaua, ASA Târgu Mureş, but he refused, eventually going to Dinamo who gave four players to Universitatea Cluj in exchange for him, including Florin Prunea. He spent two seasons with The Red Dogs, in the first one he did not win any trophies and reached the quarter-finals in the 1988–89 European Cup Winners' Cup where they were eliminated on the away goals rule after 1–1 on aggregate by Sampdoria and in the following season the club won the title and the cup with Sabău playing 24 Divizia A matches in which he scored five goals and scored one goal in the 6–4 victory from the 1990 Cupa României Final against Steaua București, also appearing in 7 matches in which he scored two goals in the 1989–90 European Cup Winners' Cup where Dinamo reached the semi-finals where they were eliminated after 2–0 on aggregate by Anderlecht. After the 1989 Romanian Revolution, Sabău was transferred by Dinamo at Feyenoord for over one million$, where he spent two seasons, winning two cups and one supercup, also helping the club reach the 1991–92 European Cup Winners' Cup semi-finals, appearing in 3 matches from the campaign and was colleague in his second season with fellow Romanian, Marian Damaschin. In 1992 he was sold by Feyenoord to Mircea Lucescu's Brescia for over one million€, playing two seasons in Serie A and two in Serie B a period in which he was declared the best right midfielder from Serie A in 1993, managed to win the Anglo-Italian Cup in 1994 and was colleague with compatriots Gheorghe Hagi, Florin Răducioiu, Dorin Mateuț and Dănuț Lupu, the team's nickname being "Brescia Romena". In July 1996, Lucescu signed with Serie A club, Reggiana, bringing Ioan Sabău with him, but the team finised on the last place in the end of the season. After another Serie A season at Brescia, Sabău returned to Romania in 1998 at Rapid București, at the advice of coach Mircea Lucescu, appearing in 22 matches in which he scored one goal in the 1998–99 season, helping the team win the first title after 32 years. In the 2000–01 season, he was a player-coach at Universitatea Cluj in Divizia C, helping the team win promotion to Divizia B, leaving shortly afterwards because of a conflict with the clubs officials. In 2001, he returned to play for Rapid for two seasons, winning the 2002–03 Divizia A title, playing 16 Divizia A matches in which he scored one goal, also winning a cup and a supercup with coach Mircea Rednic and made his last Divizia A appearance on 24 May 2003 in a 3–0 home victory against UTA Arad. He made his last appearance as a footballer at the end of the 2004–05 Divizia B season for Gaz Metan Mediaș, a team which he was also at that time its head coach. Ioan Sabău has a total of 70 matches and six goals scored in Serie A, 55 matches and six goals scored in Serie B, 39 games with 11 goals scored in Eredivisie, 172 appearances and 17 goals scored in Divizia A and 25 games played with 3 goals scored in European competitions.
