Tagliafico's potential transfer to Spain was initially considered, with Juventus showing interest in the player. However, Atlético Madrid were also in the running and had hoped to agree a deal with Lyon before the transfer window closed. Unfortunately for the Spanish club, their Financial Fair Play issues proved to be a major obstacle. With several players already signed, including Morten Hjulmand, Kang-in Lee, Cristian Romero, and Alejandro Grimaldo, adding Tagliafico would have put them over the financial limit. As a result, the transfer fell through, and Juventus also lost interest.
