CSK again invested in the older players, even they bought Pujara but don't know the actual reason for doing it because they don't have any spot for him to play. And bought K.Gowtham which also not convincing as CSK player because I thought they would buy someone who can be a match-winner like watto. The good thing is they bought Moeen Ali but they already have Jaddu so going to play with two All-rounders? 
Exactly why pujara? K.Gowtam is a good buy but they really needed a finisher who can finish alongside MS Dhoni. Moeen Ali will be the off-spinner they are lacking after Harbhajan Singh left them.
I still don't get why Harbhajan left CSK? No one bought him today. So he left for being unsold. Wow!!
