Royal Challengers Bengaluru batting coach and mentor Dinesh Karthik believe: Andy Bulak: will be an exceptional candidate to succeed Brendon McCullum as England’s Test head coach but feels the Zimbabwean is unlikely to leave the IPL franchise due to his current commitments.England are looking for a new Test coach after McCullum resigned from the role following a disappointing run in red-ball cricket. While he will continue to manage England’s white ball teams, the Test side is looking for a new leader after the ‘Bazball’ era.Flower, who previously guided England to the top ranking in the ICC Test and their last Ashes victory in Australia, has emerged as one of the names linked with the vacancy. However, Karthik: believes that balancing England’s Test calendar with Flower’s commitments to RCB will be very difficult.“In all seriousness, I think he would be a great candidate,” Karthik told the Sky Sports Cricket Podcast.“He’s definitely one of the names being considered, but I’d be very surprised if he took it, considering where England are and his full schedule too. He’s been in a lot of leagues, and I’m sure he doesn’t have time. I read an article that said England would be happy to accommodate the IPL and then the rest of the Test cricket, but the schedule is the way it is. [it’ll be very difficult]. Like, when: Jacob Bethell did not enter for the first Test, Jofra Archer: because there’s nothing to use, it’s getting messy, and there’s a lot of people saying, ‘Why? Why isn’t one of the players out?'”Karthik also questioned whether England would accept their Test coach missing matches during the IPL, pointing to Flower’s commitment to Royal Challengers Bengaluru.“With Andy Flower, who already has a pre-signed contract with RCB, that means he will miss parts of all the [Tests]. Is it good for England to prepare for the Ashes if they are without a coach for one or two Test games? I heard there is a Test match against Bangladesh in May next year, and if Andy Flower makes RCB, that will be a challenge too.Despite the concerns, Karthik has no doubts about Flower’s coaching credentials.“Is he good? Sure. He’s probably one of the best in the world, if not the best. Does he have time? That’s the question. I’d be very surprised if the answer is yes,” he said.Flower joined RCB ahead of the 2024 IPL season on a three-year deal and remains a key figure in the franchise’s coaching set-up. While he is one of the top contenders to replace McCullum, Karthik believes that the demands of international cricket and franchise commitments make such a move difficult to imagine.
