You can't compare the Monk to Bahjji! They are very diffeent bowlers.
Bhajji is quicker through the air, relies more on top spin and bounce, and has a doosra.
Monk is slow and loopy, gives a lot of revs and gets an appreciable amount of turn, and gets srong away drift with the old ball.
Very different! And seeing how succesful Gayle was (ie, not very), Bhajji isn't needed. For now.
And Sreesanth is gold. He can strike when rest of the team's morale is down, when they are tired. Just before the end of a session, when the batsman's guard is down, with new ball or old. I mean, he turned the match with Sarwan's and Lara's wicket! He bowls with high intensity throughout. He is a match changer and a match winner. We don't have any other bowlers like that. Kumble maybe, but he is more consistent and hard working. Pathan could be counted, but that is only with the new ball.
