FC Köln, Karlsruher SC and 1860 Munich in Germany and Roma in Italy, and spent a season apiece with Juventus, Borussia Dortmund and SV Salzburg.

Born in West Berlin, Häßler spent his early playing days in the youth team of Reinickendorfer Füchse.

Soon after winning the 1990 World Cup with the Germany national team in Italy, Häßler transferred to Juventus for a sum of DM15 million.

In the following three years, Karlsruhe and its new key player achieved positions in the upper third of the table which resulted in UEFA Cup participations in 1996–97 and 1997–98.

However, shortly after this win Häßler received the first big injury in his career when he broke his leg in a league match against Fortuna Düsseldorf.

There he met the later assistant of the Germany national team, Michael Skibbe, then with 32 years the youngest head coach in the history of the Bundesliga.

Disappointed about his season in Dortmund, Häßler left the club towards Bavaria and signed a contract with TSV 1860 Munich.

Although he is considered one of the best German footballers of all time, he did not win a single major club title, having lost the UEFA Cup final with 1.

He displayed a specialty for scoring spectacular free kicks, tireless stamina and dazzling dribbling sprees, as Germany went on to reach the final of the tournament.

[4] A world-class playmaker,[5] who was considered to be one of the best German players of the 1990s,[6][7] Häßler was a talented, dynamic, and creative midfielder, with quick feet and a good right foot, who stood out for his speed, energy, and constant movement across the pitch.

A diminutive player, despite not being particularly physically gifted, he was known for his technique and dribbling skills, as well as his ability to score goals or provide assists for teammates;[8][9][10][11][12] he was also a free kick specialist, and stood out for his leadership throughout his career.

In February 2016 Häßler joined eighth division Bezirksliga side Club Italia Berlin as their new coach with the self-declared aim of eventual promotion to the 3.

In 2017, Häßler participated in German television show Ich bin ein Star – Holt mich hier raus!.
