The Red Devils announced that the former Zamalek boss rescinded his contract because of 'urgent family problems'.

"To take over Ahli, I would have to be sharp all the time," Vingada told the club's official website.

"The past few days were really tough for me and for my family as well, and I don't think I can do my job competently under such circumstances.

"I need to move to Portugal in the immediate future to stand by my family, and I hope I can terminate the agreement we reached without troubles.

"I apologize for my decision, but I had no choice."

However, FilGoal.com learnt that Vingada backtracked on the Ahli job after he failed to get along with the club's football committee.
