According to reporter Uriel Iugt, William and Gremio reached an oral agreement on visa-free matters.
William left Fulham this summer to become a free agent. Gremio is interested in the 37-year-old Brazilian winger. The two sides have reached an oral agreement on the signing of the contract until December 2026.
William returned to Fulham without a sign-off in February this year, playing 10 Premier League games for Fulham, without scoring or assisting.
