Glenn McGrath believes that Jasprit Bumrah must put in extra effort off the field to ensure his body remains in peak condition. The Indian pacer is currently recovering from a back injury sustained during the Border-Gavaskar Trophy and is undergoing rehabilitation. As a result, he is set to miss the first few matches of the Indian Premier League (IPL). Speaking about Bumrah’s recovery to Times of India, McGrath stressed the need for him to be mindful of his workload and smarter in managing his fitness. "He puts more stress on his body than the other bowlers. He has found ways to manage it, but unfortunately not all the time. He has done it before; he will know better than anyone about the recovery time, the time in the gym. He is not as young as he used to be, so he has to be smarter about what he does," McGrath told the Times of India. 'My fuel tank was bigger than Jasprit Bumrah’s' McGrath further advised that Bumrah should only return to the field when he is fully fit and should take the time to understand his body better. He compared a fast bowler’s fitness to maintaining a car, stressing the importance of consistent conditioning. "He has to work even harder off the field. Being a fast bowler is like driving a car. If you do not top it up with fuel, you are going to run out of fuel sooner or later. My fuel tank was bigger than Jasprit’s because I did not bowl as quickly as him. These guys know how they work at their best. If India are under the pump, they need him," McGrath added.

"Their IPL and T20 cricket has had a positive impact on one-day cricket," McGrath stated. He also acknowledged that India remains a dominant force in world cricket. "India knows the ODI game very well. It is a challenge for other teams to come over to India and play well. I like them to be challenged, but India are a quality team," he added.
