India is according to me the best touring team right now in the world. They have beaten australia in australia and here in england as well they are looking the much better team than england. I think there is more victories to come for india in this series.
I would still rate New Zealand one level above India. And the Indian batsmen have no clue about facing the Kiwi pacers. New Zealand currently has the best pace bowling attack for any of the test teams right now. And their batting is also quite strong, with Kane Williamson and Ross Taylor adding the experience and Devon Conway/Tom Latham complementing them. And I am sure that England would be a very different team, once Ben Stokes and Jofra Archer recover from the injuries. They were without two of their best players.
No team can claim that they are best touring team. Having said that this Indian team has some chance if they win in England and SA too.
Some stats (India-NZ) in SENA countries.
-Aussie beat NewZealand for fun, they didn't won single series against Aussie in last 2 decades. India won last 2 series in Australia.
-New Zealand yet to register their first test series win in India. India on the other hand won at least 1 series in New Zealand back in 2008-09.
-Kiwis yet to open their account against South Africa (home-away). India is equally shit against Proteas when playing away, not in home tho.
-In England both India and Nz won 3-3 series, although will rate kiwis slightly better in England.
