Egypt head coach Bob Bradley has insisted there will be "no margin for error" when his side look to maintain their 100 per cent winning record in FIFA World Cup qualifying.
The Pharaohs currently top Group G with six points after beating Mozambique and Guinea in their opening two encounters and will welcome Zimbabwe in Alexandria as they go in search of a third victory.
Despite tomorrow's opponents lying five points adrift of his men, Bradley will not take the challenge lightly as they seek to extend their advantage at the top to five points.
"We've won nothing yet," the former USA coach told cafonline.com. "After the Zimbabwe game we have two more games in June and everything could happen.
"But I believe winning on Tuesday will open the door for us to win this group and qualify to the final qualifying round. There are no margins for error in this match."
Egypt have not qualified for the FIFA World Cup since 1990 and Bradley admits his players would relish the chance to represent their country in Rio de Janeiro next year.
"Those players are very strong, mentally and technically. Playing in the World Cup is the ultimate dream for all of them," he added.
