Shoaib Akhtar's knee injury and an unforgiving schedule, though, makes their task even harder. For a team who are yet to prove they can compete against the top teams, two of their three remaining games are against the most formidable sides of the tournament - Rajasthan Royals and Kings XI Punjab. Kolkata's inconsistent batting remains their main bugbear with the troubles starting at the top - seven different combinations in 11 games have yielded less than 20 runs an innings.
With all their departments firing and comfortably perched at the top of the table, the Rajasthan Royals have no such concerns. A win against Kolkata will guarantee a spot in the final four, and with it an opportunity to give some of their top players a break in the remaining three league games.

Watch out for
The clash of the captains - Shane Warne and Sourav Ganguly had a war of words after Ganguly refused to walk when a catch was claimed at midwicket in their previous encounter.
Graeme Smith against the Kolkata pace attack - Smith has been hard to dislodge and has orchestrated several of Rajasthan's successful chases. Who wins the battle between him and Kolkata's formidable fast bowlers could be a key factor in the match's result.
Team newsIf Shoaib's knee injury doesn't heal in time, Umar Gul is likely to get a look in after missing three games. While the batting continues to struggle, a lack of quality alternatives could see Kolkata go in with the same batsmen.
Kolkata Knight Riders (probable):
Unless Rajasthan want to give some of their regulars a rest, they could go in with the same XI that clinically dismantled Bangalore on Saturday.
Rajasthan Royals (probable):
