Senegal head coach Aliou Cisse is considering changes for his side’s must-win World Cup Group A clash against Ecuador on Tuesday.

Having lost to the Netherlands in their opening match, a 3-1 victory over Qatar kept the African champions’ hopes of advancing to the last 16 alive but Ecuador’s draw against the Oranje gives the South American’s the edge at Khalifa International Stadium.

Only a win will be enough for Senegal to progress to the knockout stage for the first time since reaching the quarter-finals in 2002, their first World Cup, and they will have to beat South American opposition at the World Cup for the first time having lost on two such previous occasions (Uruguay in 2002, Colombia in 2014).

Cisse is pondering tactical tweaks for the crucial clash.

“We have to think about the appropriate approach to the last match. We need to win to qualify for the last 16,” Cisse said.

“Our concentration must be better as we could have avoided the goal that we conceded [against Qatar], but the Ecuador match will be different.”

Coping without injured superstar Sadio Mane has been an issue for Senegal but the team shared scoring responsibility against Qatar, with three different scorers for the first time in their World Cup history.

Ecuador’s defense has proven resolute this far, facing seven shots in two games, and this encounter marks the first time they have faced an African nation at the World Cup.

At the other end, Enner Valencia is looking to become just the second player to score seven straight goals for a single nation at a World Cup.

Valencia already has three in two appearances in Qatar and head coach Gustavo Alfaro was full of praise for the experienced forward.

“[Valencia] is a top-level player when he wears the Ecuador jersey. I tell him that he will be successful in the World Cup even if he wasn’t so good in the qualification campaign,” said Alfaro.

“He is going through such a good spell. He is the captain.”

Players to Watch

Ecuador: Enner Valencia

Who else? Should he score Ecuador’s first goal in the match against Senegal, the former West Ham and Everton man will equal Oleg Salenko’s record for Russia in 1994 by scoring his nation’s last seven at the World Cup.

His six goals in a row have come from just nine shots on target, converting 67% of those, and will have a huge part to play if Ecuador is to advance past the group stage for the first time since 2006.

Senegal: Ismaila Sarr

Yet to score at the World Cup, Ismaila Sarr has had more shots for Senegal than anyone else (six), though only one of those has been on target – which came in his side’s 3-1 victory over Qatar last time out.

Sarr remains a key attacking outlet for the African champions, with eight touches in the opposition box in the defeat to the Netherlands, more than anyone else, and four against Qatar, the second-highest in his side.

Ecuador vs Senegal Prediction

La Tri has looked solid in their first two games of the competition and will be looking to remain undefeated in the group stage of the FIFA World Cup for the first time in their history. Valencia has scored all three goals for them in the competition and this reliance on the veteran might prove costly in the game against Senegal.

He faces a race against time to be fit for the game but should be able to at least make an appearance in this match. Ecuador has a strong defensive lineup and is not expected to concede a lot of goals.

The Lions of Teranga failed to keep a clean sheet against Qatar in their previous outing and are unlikely to stop Ecuador from scoring in this match. Both teams look evenly matched on paper and, given their form, we expect them to play out a draw.

Prediction: Ecuador 1-1 Senegal
