Can Jadeja reduce pace of his deliveries in English conditions to remain effective?

Ravindra Jadeja's inability to make decisive inroads on the fifth day of an up and down Headingley track did raise eyebrows and questions of him not being as effective as he is on Indian turners.

The fifth day of the opening Test saw unhinged Ben Duckett reverse sweep Jadeja out of the match in a chase of 371. He could not turn the ball from the rough created outside the left-hander's off-stump by the Indian pacers. As India team is pondering over best combination, question arises if Jadeja will play at Edgbaston after a match-haul of 1/172 in 47 overs across both innings. He managed 1/102 in 24 overs on the fifth day track.

If India are without Jasprit Bumrah, then logically, they shouldn't be playing two finger spinners in Jadeja and Washington Sundar. In that case Kuldeep Yadav and Washington (whose batting skills match Jadeja's) can play as it would be difficult, to stop rampaging English batters on a good batting surface.
