Sunderland’s 3-0 victory over Everton at the Stadium of Light in the Premier League on Wednesday evening saw them retain their top-flight status for one more season at least.
Striker Jermain Defoe has been key to the Black Cats’ survival, scoring 15 goals and creating 21 chances in 33 Premier League appearances.
Former Liverpool defender Carragher has highlighted the importance of Kone for Sam Allardyce’s side.
“Kone, who scored two of the three goals to sink Everton, was one of three men Allardyce spent money on in January - the others were Jan Kirchhoff and Wahbi Khazri - and the Ivory Coast defender certainly played his part in the revival,” the former England international wrote in The Daily Mail.
“Of course, Jermain Defoe’s goals were critical but Kone has been part of a defence that has kept four clean sheets in the last seven matches to get Sunderland over the line with a game to spare. Allardyce can reflect on a job well done.”
Kone joined Sunderland from French club Lorient in the January transfer window and has played well for the Black Cats.
The central defender has scored two goals and created five chances in 14 Premier League matches this season.
The 27-year-old Ivory Coast international has a pass accuracy of 64% and a shot accuracy of 40%, and has won 48 headers, three dribbles and 14 tackles.
Sunderland will take on Watford away from home at Vicarage Road in the Premier League on Sunday afternoon.
