The opening match of the IPL 2019 will be a high intensity affair between defending champions Chennai Super Kings and Royal Challengers Bangalore at the M A Chidambaram stadium here on Saturday (March 23). Here's the preview of the much-anticipated clash between two heavyweights.They are the most successful team in the IPL history with three titles and a few more final appearances and only Mumbai Indians match them for the number of titles. They may be on the wrong side of the 30s but age is a mere number when it comes to performance. They had proved it with a title win last year and would be hoping for an encore in this edition.
