No question SAF could possibly stay for a couple more seasons, he still seems to have the health the energy and desire to compete. Yes, United supporters United are 7 points clear and playing well at the moment but no one is bigger than this football club not even SAF and there should be a plan in place especially at this stage of his career, one never knows what is around the corner so what should the club do, wait until it is too late, wait till he collapses somewhere? There are cracks in his armour, there are signs of aging yet he could quite possibly stay another 5 years which I would not mind but only if he had the staff around him to help. I don't know if Moyes would want to work under SAF but I would bring him in and allow him to work as SAF's number 2, let him rub shoulders with Fergie groom him to take over, yet at the same time give him the freedom to bring in and develop players, he is brilliant at finding and developing players. No one will replace SAF he is one in a million but United need to develop an exit strategy for him.
