Tottenham managing director Fabio Paratici may have to step away from his current role after Fifa extended an initial ban in Italy worldwide.
Paratici was given a 30-month ban in January after his former club Juventus were found guilty of false accounting.
The 50-year-old served as sporting director and managing director at Juventus before joining Tottenham in June 2021.
Paratici and Juventus have both appealed the decision.
Paratici's initial ban only applied to Italian football, meaning he was able to continue working at Tottenham.
However, the extended ban comes as Tottenham search for a new manager following the departure of Antonio Conte.
Conte left Spurs on Sunday with the club fourth in the Premier League, but having been knocked out of the Champions League and FA Cup in recent weeks.
Paratici told the club website on Tuesday that he and the club were "focused" on moving forward and finding a replacement.
"Fifa can confirm that following a request by the Italian FA (FIGC), the chairperson of Fifa disciplinary committee has decided to extend the sanctions imposed by FIGC on several football officials to have worldwide effect," a statement from the world's governing body read.
The entire board of the Serie A club, including president Andrea Agnelli and vice-president Pavel Nedved, resigned in November as a police investigation into the club's transfer activity continued.
Juventus were subsequently docked 15 points by the FIGC in January. The Serie A giants were accused of fixing their balance sheets by artificial gains from club transfers.
