Johannesburg: Nasarawa United of Nigeria were bundled out of the CAF Confederation Cup this weekend after a late second-half collapse triggered a 4-1 defeat by CS Constantine in Algeria.
The situation was promising for the West Africans in the last-32 second leg with 13 minutes remaining as they were drawing 1-1 and one goal ahead on aggregate.
Having snatched a 1-0 victory at home last weekend, Nasarawa also had an 'away' goal advantage, meaning the hosts had to score at least twice.
France-born Constantine coach Didier Gomes Da Rosa then made two inspired substitutions, introducing Ahmed Messaida and Mourad Meghni.
Both scored within minutes of coming off the bench to turn the tide and Malagasy Paulin Voavy added a fourth goal to complete a dramatic triumph for the 120-year-old Algerian club.
Yacine Bezzaz converted an early second-half penalty to open the scoring in Constantine and Bature Yaro levelled through a spectacular long-range shot.
The 4-2 overall beating for Nasarawa ended Nigerian interest in the three-round qualifying stage of the African equivalent of the Europa League.
