for six months and wanted to test me before maybe they could sign me.”

Jean-Kevin Augustin joined Leeds on loan on 27 January 2020 until the end of the season with the club having the option to sign him permanently in a £17.7m deal. Leeds had the obligation to complete a permanent transfer due to a clause on the club triggering a promotion clause at the end of the 2019/20 season. However, Leeds claimed extenuating circumstances surrounding the COVID-19 pandemic which rendered the deal redundant as Leeds were not promoted by June 30 as the club still had six fixtures left to play. Augustin's loan period ended and he was released by the club. Leipzig argue that under the "spirit of the rules", the transfer should have taken place, as football contracts specify 30 June as the "end of a season". FIFA confirmed on 8 December 2020 that Leipzig had filed a claim against Leeds over the cancelled transfer. On 8 June 2021, a FIFA court sided with Leipzig and against Leeds. A ruling at the The Court of Arbitration for Sport decided Leeds lost their case and ordered Leeds to pay £18m (£17.7m + 300,000 in interest) to Leipzig on Nov 4th 2022. Leeds lodged an appeal over the CAS ruling.
