JOHANNESBURG. With just three games remaining in the third round of African qualifiers for the 2014 Fifa World Cup Brazil, several favourites are in danger of missing out on a ticket - even before the final round of qualifying commences.North African giants Tunisia and Egypt, as well as surprise package Congo could become the first countries to book their place in the final round of qualifying should results go their way this weekend. The ten group winners will advance to the third round, where they will be drawn into five ties, with the winners of the two-legged matches qualifying for Brazil.Crucial matchGabon          vs     Congo When the draw for the second round of African qualifiers was made, Congo were placed in pot four as one of the weakest teams in the draw. This weekend the Red Devils could become the first African country to book their place in the final round of qualifying, leaving them just two games away from a first-ever appearance at the Fifa World Cup. Ahead of a tricky away match in Gabon they lead Group E by six points and would qualify with a win if the match between Niger and Burkina Faso ended in a draw.Coach Kamel Djabour will, however, have to take on the Panthers without a star player as Christopher Samba withdrew from the squad. Also missing are Ulrich Nzamba and Dyzaiss-Lys Mouithys, who have been replaced by Nkolo Lorry and Dimitri Magniokele Bissiki. For Gabon the match is a last throw of the dice as anything but a victory will see them eliminated.It is a point the Gabon players are well aware of. "We know what awaits us, we will have to be strong mentally, and attack at 100 mph. We have to win if we hope to qualify,” said goalkeeper Didier Ovono.ElsewhereEgypt can give their long-suffering fans something to smile about as they are one of three teams capable of qualifying for the final round this matchday. The Pharaohs are away to Zimbabwe, whose coach Klaus-Dieter Pagels said that their close 2-1 defeat against Egypt in March gave them confidence. "If we can improve, especially in defence, then we will win this game. We had the chance to win there and here we can win as well.”Egypt’s task in Group G has not been made easier by the injury-related withdrawals of Zamalek duo Mohamed Abdel-Shafy and Nour El-Sayed.A win for Egypt and a result for Mozambique in Guinea would guarantee the north Africans a place in the next round. The Pharaohs could be joined by Tunisia, who would go through if they win their Group B clash in Sierra Leone and Equatorial Guinea fail to beat Cape Verde Islands. Tunisia coach Nabil Maaloul will be without captain and goalkeeper Aymen Mathlouthi, who pulled out of the squad after picking up an injury last weekend.In Group C, Ivory Coast are neck-and-neck with Tanzania, and the Elephants, who have a point more than the Taifa Stars, are away to Gambia, while Tanzania travel to Morocco. Sabri Lamouchi has called up newcomers Serge Aurier and Norwegian-born Mathis Bolly, but left out Didier Drogba.The former French international in his first management position said that he will not underestimate Gambia. "We would make a big mistake by thinking it is going to be a walk in the park. We need to be much focused because in Gambia, on a tricky pitch, it is going to be tough.”A similarly close battle is developing in Group D, where Zambia lead Ghana by a point. The Chipolopolo are at home to Lesotho on the weekend, while the Black Stars travel to Sudan. Midfielder Rainford Kalaba will miss the game against Lesotho after aggravating a calf injury. Cameroon’s new coach Volker Finke is away in Togo for his first competitive match in charge of the Indomitable Lions, who lead Group I by a point from Libya.Cameroon star striker Samuel Eto’o will not be available for the game in Lome after injuring himself in the Russian cup final with his club Anzhi Makhachkala.
