Patel, whose parents immigrated to New Zealand in 1996, picked up all four wickets on a track aiding the spinners on Friday to finish with figures of 4-73, taking all the Indian wickets to fall as they reached 4-221 largely off the back of Mayank Agarwal's gritty hundred .

At one point, Patel's figures read 12-7-14-3, which included the wickets of Virat Kohli and Cheteshwar Pujara for ducks.

"This is what dreams are made of. To be out here and pick up four wickets on the first day is pretty special," said the 33-year-old.

"At the same time, the job is only half done. So we have got to make sure we turn up tomorrow and really work hard for the last six wickets."

Ajaz didn't receive much support from his fellow two spinners, who went for 66 runs off their 12 overs, but he revealed that one of them, Rachin Ravindra, had been unwell.

"Everyone was out there working hard and poor old Rachin came down with a bug this morning," Ajaz said.

"He fought his way out there throughout the day. It is pretty impressive from the young man to be able to stick it out. It really shows his character."

Tomorrow is a new day. We start fresh, and we go again. It is just about bowling in partnerships. I am sure we will turn up tomorrow."

Agarwal came to India's rescue with an unbeaten 120 after completing his fourth Test hundred.

A square-driven four off seamer Daryl Mitchell took him to three figures and the 30-year-old leapt and punched the air to celebrate his first Test ton since he scored a career-best 243 against Bangladesh in 2019.

"It's an amazing feeling to get a century in Test cricket and to get it in Wankhede is extra special," said Agarwal.

"How we start (tomorrow) is crucial, the focus is that. The first session we want to play it out, the wicket is going to get harder and harder to bat on."
