Kallis must be managed

Manage him correctly and u get da best out of him,at 37 nw i think let him play only a few,but he should check his fitness first and foremost, if his desire is there lt him play, look SA PROTEAS didnt respond well but they managed to win the 20series,move on to the next level, TESTS for KALLIS will prolong his career, the other generations said goodbye to the Oneday Games  and some just play TESTS,  even with KALLIS in the line up, doesnt guarantee victory in the next worldcup, coz he knows hw badly he wants to win it.......
