Cricket Poll : When can we see 'Dominating or Aggressive Character' of a Player?

I think it can be seen when the oppositions start sledging because that's the time when the player is really angry and he becomes aggressive and dominating. In a pressure or tight situation, some players may be dominating and some may be aggressive and some may be nervous. But in the first instance, every player is tend to get dominating and aggressive. Its upon the player to control himself and not make a fool out of him.
