Now in third test India will go with some advantage they are doing very good job in batting and bowling and Lankan's batsman's badly down by moral they need to do some hard work in third test otherwise India is going to win series very easily
You cannot say anything about India , why srilanka was also won first match from losing to win unexpected match, even then they lost 2nd test match to India. so the rule is in cricket you cannot expect what you expect and you will see what you don't expect
This Test Series is very much important for Virat Kohli to win as he wanted to make his Captaincy as a Usefull captain for India after MS Dhoni.
Yes what you said is correct. The previous match winning will give you some confidence level to enter next match is for sure but in cricket game every match is different. On that given day who ever outperform they will win the match. SL also got advantage of home ground so India has to put up a complete team effort to win the last match.
