Sarr scored his penalty in the 44th minute having earned the spot-kick himself, but Ecuador, who needed only a draw to reach the knockout rounds, equalised through Moises Caicedo.
The African champions finish second in Group A with six points from their three matches, one behind winners Netherlands and two ahead of Ecuador, whose tournament held much promise but has ended in bitter disappointment. Idrissa Gana Gueye fired wide early and Senegal striker Boulaye Dia had a superb chance when he had a clear sight of goal, but skewed his shot wide of the far post.
The flow of the game changed in the second period as it was Senegal who were happy to sit back and a desperate Ecuador pressed for the equaliser.
Izwe lethu ma-Afrika.
All the best guys..my African my pride!!✊🏻✊🏻⚽️⚽️❤
