For me, if it is NZ vs AUS, then both will be having equal chances. They will be playing in Lord's and both the teams won't have the home advantage. Australia is over-dependent on a few players, such as Steve Smith and Marnus Labuschagne. On the other hand, New Zealand is a well balanced team and they are not dependent on anyone. But then, Australia have players such as Steve Smith, who can win matches in his own. NZ lacks a player of that calibre. That said, I don't want to make any predictions until the India vs England series is over.
Right now we are just 36 hours away from second test match between India and England any one give update about weather pitch could be very good for all supporters of this test match.
