Sudanese Abubakar Kaki has proven to be a force to reckon with in 800m and Rudisha cannot ignore him.
Kaki has been in Kenya for training and had pitched camp there for the better part of December 2011 before the World Indoor Championships.
He did put Rudisha on notice that all will not be smooth sailing at London Olympics when they meet for the showdown. He is listed second in the current World 800m ranking.
