The Manchester City man says the Elephants have plenty of work to do ahead of the upcoming Africa Cup of Nations, despite winning their latest friendly against Egypt.
A brace from Arsenal winger Gervinho and strikes from Lacina Traore and Didier Ya Konan eventually finished off the Pharaohs, but the Manchester City man was unhappy with the Elephants' defensive showing.
“Although we beat Egypt 4-2 I think we still have some serious problems, especially in the defense,” Toure told the Ivorian media. “We have to correct our lapses and play very deep right from the defense to stop the opposition from getting too close.
"We also need to correct conceding dangerous corner kicks and throw-ins and then engage the midfield to play high and hard and form the first defensive line. In official competitions there are mistakes you don’t make or you pay for it dearly. I’m not too satisfied with our showing, but since we have more time to fine tune, I hope we’ll be able to correct that.
The Elephants will leave for South Africa on Thursday and open group play against Togo next Tuesday. Tunisia and Algeria are the other teams in Group D.
