The 2019–20 EHF Champions League was the 60th edition of Europe's premier club handball tournament and the 27th edition under the current EHF Champions League format.[1]
Because of the COVID-19 pandemic in Europe, the knockout stage matches were postponed and later cancelled. The Final Four, which took place at the Lanxess Arena in Cologne, Germany, was moved from May to December and was contested by the top two teams from Groups A and B – Barça, Paris Saint-Germain, THW Kiel and Telekom Veszprém.[2][3] As a result, reigning champions Vardar were not able to defend their title.
The competition begins with a group stage featuring twenty-eight teams divided in four groups: Groups A and B contain eight teams, while Groups C and D contain six teams. Matches are played in a double round-robin system with home-and-away fixtures. In Groups A and B, the top six teams qualify for the knockout stage, with teams ranked 2nd–6th entering the round of 16 and the group winners advancing directly to the quarter-finals. In Groups C and D, only the top two teams advance to a compete in a two-legged play-off round, with the two winners going through to the knockout stage round of 16.
The knockout stage includes four rounds: the round of 16, quarterfinals, and a final-four tournament comprising two semifinals and the final. In the round of 16, twelve teams (ten from Groups A and B, and the two play-off winners from Groups C and D) are paired against each other in two-legged home-and-away matches. The six aggregate winners of the round of 16 advance to the quarterfinals, joining the winners of Groups A and B. The eight quarterfinalist teams are paired against each other in two-legged home-and-away matches, with the four aggregate winners qualifying to the final-four tournament.
In the final four tournament, the semifinals and the final are played as single matches at a pre-selected host venue.
A total of 35 teams from 21 countries submitted their application for a place in the competition's group stage before the deadline of 12 June.[4] The final list of 28 participants was revealed by the EHF Executive Committee on 21 June.[5]
