1) Two relatively mediocre sides pitting against each other
India and England, both teams have been struggling with their form in their respective past fixtures. What India are dealing with is the horror of their last tour to England in 2011. To say that they were decimated would be an understatement. India lost the four Test match series 4-0 and then went on lose the five match One-Day series 4-0 as well. Apart from this, India's horrendous performances on foreign soils have also been a worry after losing to South Africa and New Zealand in their home grounds.
Meanwhile, a lot has changed for England since that last tour as well. Back in 2011, when England had pummeled India, they had also seized India No. 1 ranking in Tests with that victory. England continued their dominance briefly but now a lot seems to have changed. This England side is suddenly looking a lot more vulnerable as was evident in their series loss to Sri Lanka,both in Tests and One-Dayers, just a few weeks back.
