At the end of the 2019 summer transfer window, German club TSG 1899 Hoffenheim showed interest in Gril.[4] However, he stayed in Bravo. But the rumors appeared again in November 2019, saying that Hoffenheim already had an agreement with Bravo for the transfer of Gril.[5] The deal was officially announced on 13 December 2019[6] and became a record deal for Bravo.[7]
Gril signed a deal with Hoffenheim until the summer 2024 but stayed on loan at Bravo for the rest of the season.[8] He played only one game during the last six months of his time at Bravo, before returning to Hoffenheim in July 2020.[9] In September 2020, he struggled with back problems which kept him out for some time.[10]
