Jorvan Vieira's spell as Zamalek coach could be over soon amid speculation that the Brazilian has decided to stay in Abu Dhabi after the friendly Matchworld Cup. Despite the impressive display against Zenit St. Petersburg, it was reported that Vieira has decided to leave the club as the Whites board did not deny the allegations. “It is true we received information that Vieira does not plan to return to Cairo but there is nothing official yet," Zamalek board member Ayman Younes told FilGoal.com. “He asked for a few days off until Tuesday. So if he doesn't return on the specified date, an immediate decision will be made by the board regarding his future." Vieira said last November that he intends to leave Zamalek amid lack of domestic football, but did not set an exact date for his exit. The former Iraq manager has been in charge of the Cairo club since August 2012, following the departure of Hassan Shehata.
