Transfer controversy In January 2020, São Paulo's Football Executive manager Alexandre Pássaro stated that the club would seek to initiate an investigation on Bissoli's signing for Athletico, saying that "If we offer a certain contract and another club offers the same or even a bigger one, São Paulo can cover the offer, and the player is obliged to stay. A year ago, we had this exact episode with Athletico-PR, who made an offer for Bissoli. We matched, they increased, we matched again, and he stayed here." Bissoli, however, refused to stay at São Paulo, and left the club when his contract expired in February 2019.
