The correct answer is None of the Above. The question is "Which Italian manager served as a mentor to Cesare Maldini during his coaching career?". The only two Italian managers mentioned in the passage are Arrigo Sacchi and Carlo Ancelotti. It is not mentioned in the passage that Arrigo Sacchi or Carlo Ancelotti served as a mentor to Cesare Maldini. So the correct answer is None of the Above.
