Former England left-arm spinner Monty Panesar feels all-rounder Ravindra Jadeja "will be the X-factor" when India take on the Kane Williamson-led New Zealand in the World Test Championship (WTC) final at the Ageas Bowl in Southampton from June 18 onwards.

Panesar said on Saturday that while a lot will depend on how the International Cricket Council (ICC) prepares the pitch for the inaugural WTC final, "spinners will also play a crucial role" in the summit clash.
