The sturdy centre back is the skipper of Senegal and is a true leader of his pride of lions.
He is the mainstay in Senegal's defence and a lot will rest on his shoulders when Aliou Cisse's men take on England. His battle with Harry Kane will be one to savour and it will be interesting to watch if he can keep the explosive Tottenham forward in check.
Koulibaly also got a crucial goal against Ecuador, which was his first-ever for his country and could not have come at a better time.

Edouard Mendy | Chelsea | GK
Edouard Mendy endured a tough start to the World Cup after committing silly errors against the Netherlands, but came back strongly against Qatar and Ecuador respectively.
He pulled off two stunning saves against the Maroons in the second half to deny them a memorable comeback, and against Ecuador he stepped up whenever his team required him to with crucial saves in the final quarter.
Needless to say, against a fiercely attacking side like England his credentials will once again be tested.

Youssouf Sabaly | Real Betis | DF
Youssouf Sabaly has hardly put a foot wrong in the World Cup. Alongside Koulibaly, he has been one of Senegal's best performers.
The right-back has won 100% of his tackles and has won 67% of his duels, which testify to his brilliant form in the defensive third.
His battle with Marcus Rashford will be an intriguing one as the Manchester United forward heads into the match on the back of a brace against Wales.

Bamba Dieng | Marseille | FW
If Senegal are trailing and in need of making a comeback, expect Bamba Dieng to come on. He has been used as a substitute who comes on just before the final quarter of a match to provide fresh impetus in the attacking third.
England's backline will be tested by his pace, especially towards the end of the match with fatigue and tired legs. He has already opened his account in this World Cup with a goal against Qatar and will be looking to add more to his tally.
Oh, and another thing – he converted his AFCON final penalty, which makes him useful in the event of a tiebreaker.
