Ex-Newcastle midfielder Tiote died after collapsing in training in China.
“I want to want dedicate this to Cheick Tiote who passed away doing what he loved,” Drogba, 39, wrote on Instagram.
“My thoughts and condolences go out to his family, the Ivory Coast and the whole of Africa, mourning the passing of one of their own.”
