These two sides have one thing in common in IPL4 - they have both lost to so-called underdogs Kochi Tuskers Kerala. But the commonalities end there. Mumbai is second only to the Kolkata Knight Riders at the top of the table with 3 wins from 4 matches, while Chennai is languishing in 7th place with 2 wins and 2 losses.
What Mumbai have going for them is that their batting appears to be incredibly robust as the top-order has come through on all four occasions. But due to the successes of the top four, especially Sachin Tendulkar (who is averaging 238!) and Ambati Rayudu, the middle and later order has not yet been tested.
Therefore, CSK M S Dhoni will have to call on his best bowling resources in Doug Bollinger, R Ashwin and Suraj Randiv to break through the top order and expose the less-experienced middle order in an obvious bid to keep the Indians to a small total.
Meanwhile, the Chennai batting line-up is looking quite solid with middle-order man Michael Hussey topping the average's charts with an impressive 91.00, followed by S Badrinath at 45.00, M S Dhoni at 36.00 and Murali Vijay at 34.25. In fact, the latter two batsmen's strike rates are over 150!
Even so, Chennai will have to be doubly wary of the destructive power of toe-crushing yorker specialist Lasith Malinga who has taken 11 wickets from 4 matches. What's more, he has received excellenet support from Munaf Patel, Ali Murtaza and Abu Nichem Ahmed who have collectively picked up 8 scalps.
