Senegal need to beat Ecuador to progress to the last-16 of the 2022 World Cup in this do-or-die clash in Group A.
The Senegalese defeated Qatar in their last game but their loss to the Netherlands last Monday means they have to beat Ecuador, who can afford a point to progress.
The South Americans did well to hold the Netherlands to a draw in their last game - and were perhaps unlucky not to emerge with all three points - and are on four points having beaten Qatar in the tournament opener.
This match will take place simultaneously with the other game in Group A, where Netherlands are firm favourites against Qatar, who are already out of their own World Cup. Here is everything you need to know.
When is Ecuador vs Senegal?
The match takes place on Tuesday 29 November at 3pm (GMT) - 6pm local time - at the Khalifa International Stadium in Al Rayyan.
How to watch
The game will be shown live in the UK on TV channel ITV4. Viewers can stream the match online via the ITVX app, formerly known as the ITV Hub.

Prediction
Senegal have nothing to lose as they look to progress to the last-16 while Ecuador can afford to draw. The fitness of Valencia could be pivotal though even without their main man, the South Americans showed enough quality against the Netherlands to merit their favourites tag here. Ecuador 2-1 Senegal.
