Al Ahly won Group B of the CAF Champions League, despite being held 1-1 by Zamalek in an Egyptian derby, and dodged a semi-final showdown with Esperance of Tunisia.
The teams are chasing a place in the FIFA Club World Cup to be hosted by Japan during December, with the line-up already including Chelsea of England and Corinthians of Brazil.
Ahly completed their six-match schedule with 11 points, one more than four-time African champions Mazembe, after three victories, two draws and a loss.
Chelsea came third with nine points, a creditable achievement in their first Champions League appearance, and 12-goal Emmanuel Clottey is likely to finish leading scorer this season.
Clottey scored hat-tricks against former Champions League winners Raja Casablanca of Morocco and Zamalek during his campaign and will line up for Esperance next year.
