Brazilian midfielder Arthur Melo arrived in Europe in 2018, moving from Gremio to Barcelona where he spent two years before joining Juventus. Noted for his passing accuracy and breaking defensive lines, he arrived as a loan signing at the end of the summer 2022 transfer window, with an option to buy. Melo came off the bench to play the last thirteen minutes of a 4-1 defeat at Napoli in the Champions League on 7 September 2022. That turned out to be his only first team appearance of a loan spell that was interrupted at the beginning of the following month by the need for surgery on a thigh injury. He remained on the sidelines for four months and when he returned to fitness was included in five matchday squads but never made it off the bench.

With Liverpool certain of finishing no higher or lower than fifth, there was speculation that Melo might be given an outing in the final game of the season at already relegated Southampton. However, he was not included in the starting line-up, writing in response on Instagram: "Never complain, just thank for all that God has given me". Juventus loaned him to Fiorentina for 2023/24. His time there was far more rewarding, appearing 33 times in Serie A and starting the Europa Conference League final, in which they were beaten 1-0 by Olympiacos. Melo then had further frustration in 2024/25 when he was deemed surplus to requirements by Juventus and forced to train alone for the first half of the season. On 1 February 2025, a loan deal with Girona of La Liga was agreed. He made 15 appearances in La Liga and was loaned out again for 2024/25, this time to his boyhood club Gremio.
