CAF Champions League Preview: Al Ahly, Raja Casablanca out to overturn deficits
CAF Champions League holders Al Ahly face an uphill task if they are to qualify for the second round of this year's tournament.
The Egyptian outfit overcame Orlando Pirates 3-1 on aggregate in last year's final to claim the title for the eighth time in their history.
However, Mohamed Youssef's men head into the second leg of their tie with Tanzanian side Young Africans 1-0 down following a disappointing first leg.
Defender Nadir Haroub scored the only goal of the game for Young Africans, and the holders will need to improve markedly on that performance in order to avoid an early elimination when they meet for the return leg on Saturday.
Another side surprisingly behind in the tie after the first leg is Raja Casablanca.
The Moroccan side surprised everybody at the FIFA Club World Cup in December, reaching the final with wins over Monterrey and Atletico Mineiro, before succumbing 2-0 to favourites Bayern Munich.
But Faouzi Benzarti's men will have to come from behind if they are to have any chance of returning to that competition following a 1-0 loss to Horoya of Guinea.
By contrast, five-time champions Zamalek have a 1-0 advantage in their tie with Kabuscorp of Angola, while last-season's semi-finalists, ES Tunis, have the benefit of away goals after a 3-2 win at Kenya's Gor Mahia.
Ivorian side Sewe Sport's prospects of qualifying for the next round hang in the balance on the back of an enthralling 3-3 draw in the first leg clash with Barrack Young Controllers of Liberia.
The winner of that tie faces a meeting with either two-time winners TP Mazembe or Les Astres of Cameroon, who are locked at 1-1 after the first leg.
Meanwhile, ES Setif, Leopards de Dolisie and Kaizer Chiefs all have one foot in the next round thanks to easy first-leg victories over ASFA-Yennenga, Primeiro de Agosto and Liga Muculmana respectively.
Cotonsport reached the last four in 2013 but head into the second leg trailing Flambeau de l'Est 1-0, however, 2006 finalists CS Sfaxien host Dedebit leading 2-1 from the first game.
It is all to play for in the ties between Dynamos and AS Vita club and Stade Malien and Al Hilal Omdurman, which are both goalless ahead of the decisive leg.
Elsewhere, Real Bamako hold a 2-1 lead over Enyimba, Berekum Chelsea and Al-Ahly Benghazi are level at 1-1 and Nkana and Kampala City Council face off again following an entertaining 2-2 draw in the first leg.
