According to Globo.com, Avaí has signed William from Cruzeiro. Avaí announced the signing of the 20-year-old left-back from the Cruzeiro youth system on a definitive contract until the end of 2028. The player, who was a champion of the Copinha, joined Cruzeiro's academy from Ponte Preta in 2022. William is registered in the Daily Information Bulletin (BID) to make his debut for Avaí, which will also be his professional debut because he did not get an opportunity with Cruzeiro's first team. The club is also negotiating with Cruzeiro for another player, the defender Pedrão.
