The winners of the North African showdown in central city Marrakech will secure one of three slots reserved for Africa at London 2012, while the losers will get a further two chances to reach the games.
There is a third-place play-off against Gabon or Senegal at the same venue on Saturday with another invitation to England at stake. And, the losers will get a final shot at qualifying next April against an Asian country.
Ghana were shock casualties in the elimination process and 2008 Beijing Olympics silver medallists Nigeria finished only third behind Senegal and Morocco in Group A last weekend. Egypt, meanwhile, topped Group B with Gabon unexpected runners-up ahead of more fancied Côte d’Ivoire and South Africa - the only country not to win a pool match at the first African Under-23 Championship.
Morocco and Egypt have identical records of two victories and one loss each going into the semi-final match, while the defensive strength of the sides is similar in that they both have conceded just one goal in three matches. Less impressive is the number of goals scored, with Egypt averaging just one per game and Morocco not even reaching that modest level, managing just two in three outings.
Ahmed Magdy snatched the Baby Pharaohs winner against Gabon and Mohamed El Niny and Mohsen Marwan were on target in a convincing triumph over the South Africans.
Spain-based Abdelaziz Barrada converted the first-half penalty that settled a tight tussle with Nigeria and substitute Adnane Tighadouini was on the field for just six minutes when he poached Egypt's winner against Algeria.
Barrada, a 22-year midfielder from La Liga club Getafe, looked a class act in the Nigeria game, while Egypt boast an outstanding goalkeeper in Ahmed El Shenawy and a dominant centre-back in Ahmed Hegazy.
