Don't get all this negativity around India, they've gone to the other big 2 nations, fought tooth and nail till the very end, and may lose only on the last day 3-1 in both series (if India lose today). These aren't bad results, especially considering in Australia you had Rohit and Kohli wasting 2 places all series, and here you've got a young captains first test series, with quite a young team around him at times.
I wouldn't be even slightly worried about what India have done the last few series. Of course the NZ series was a disaster but that's long gone now. Australia and England are 2 of the best 3 test sides in the world right now, these results away from home are nothing to worry about.
