Kallis is a valuable player

I think he is our most or probably the world's most valuable player. I understand Russell's concerns with regards to Kallis being not available for limited overs cricket, but we need to manage Kallis and his workload in all formats to ensure he plays test cricket to atleast two years after the retirement of Shatchin Tendulkar to give him(Kallis) a crack at the record of being the world's leading run scorrer in test cricket that he deserves. I think he should play the incoming tour of India 50overs and test cricket no need to abuse his abilities against Pakistan in the UAE. We need to replace Kallis with a similar type of player a proper batsman and a quality test bowler.
