Off late we have seen lot of aggression on the playing field but unfortunately it is more in the negative way. Sledging, Slapping, Needling, Gestures, Glaring Eyes, Anger, and all that shows or is deemed macho. But the real aggro is displayed by that essentially quiet and composed leg spin bowler Anil Kumble.
You will not find him giving tit for tat but he will answer his opponent in the most befitting manner. Whether it is sledging or a batsman has hit him for four, he will respond by making the opposition pay by his cricket. His cricket which is aggressive and dynamic plus intelligent gives the perfect answer to an opponent's act of aggression. This quality he has brought to his captaincy as well. Perth followed Sydney and though he was not the onfield captain, Kanpur followed Ahmedabad. These are examples from 2008. Recent memory. His illustrious career is replete with such heroic examples. And he is respected worldwide for his gentlemanly behaviour and being a true professional.
I think Harbhajan, Sreesanth and to a lesser extent Robin Uthappa should learn from this champion bowler.
