New Delhi, Apr 12: Calling the BCCI proposal to ban sledging as unrealistic, former Australian pace spearhead Glenn McGrath today said players should be allowed to exchange words on-field as long as it is within limits.

''Its okay to show aggression and have a bit of chit chat in the middle,'' McGrath told mediapersons here.''But once the match gets over and we leave the field, we are all mates,'' he added. ''Me and Vettori were talking about this last night. We had a bit of a laugh about it.'' Calling the IPL an ''exciting concept'', the 38-year-old said he is eagerly waiting for the lucrative Twenty20 league to start. ''Its an exciting concept,'' McGrath said. ''It gives you an opportunity to play with some of the best players in the world.''
