Both teams had met in the final of the 2012 Indian Premier League, when Kolkata defeated Chennai by five wickets.
In this year's Indian Premier League both were at par, winning a game apiece against each other. However, unlike the Knight Riders, CSK have played most of their group matches here and will definitely have an edge as far as familiarity factor is concerned.
Looking at the stats, Kolkata start favourites as they are on a roll after an unbeaten run in the tournament. They have, in fact, registered 14 wins in a row starting from IPL-7.
Chennai, on the other hand, had to depend on other teams' results to make the last-four stage. Led by Mahendra Singh Dhoni, the team, however, has the ability to turn it around, a quality which was evident in the semifinal against a power-packed Kings XI Punjab side last night.
