Royal Challengers Bengaluru, batting coach and mentor Dinesh Karthik I believe Andy Flower would be an outstanding candidate for success Brendon McCullum as England’s Test coach but feels the Zimbabwean is unlikely to leave the IPL franchise due to his existing commitments.England are looking for a new Test coach after McCullum stepped down from the role following a disappointing run in red-ball cricket. While he will continue to oversee England’s white-ball teams, the Test side is looking for a new leader after the end of the ‘Bazball’ era.Flower, who previously led England to the top of the ICC Test rankings and their latest Ashes triumph in Australia, has emerged as one of the names linked with the holiday. However, Karthik he believes that balancing England’s Test schedule with Flower’s commitments at RCB would be extremely difficult.“In all seriousness, I think he will be a great candidate,” Karthik said on the Sky Sports Cricket Podcast.“Certainly he should be one of the names thought about, but I would be very surprised if he took it, considering where England are and their packed schedule too. He was doing a lot of leagues, and I’m sure he doesn’t have time. I read an article that said that England will be happy to host the IPL and then the rest of the Test cricket, but with the schedule it is like that. [it’ll be very difficult]. How, when Jacob Bethell did not come for the first test, Jofra Archer Not being available, it caused a furor, and there were many people saying, “Why? How come one of the players is not here?”Karthik also questioned whether England could accept their Test coach missing matches during the IPL, pointing to Flower’s commitment with Royal Challengers Bengaluru.“With Andy Flower, with a contract already pre-signed with RCB, that would mean he would miss out on all those [Tests]. Will it be good for England in the build-up to the Ashes if they don’t have a coach for a Test match or two? I heard there is a Test match against Bangladesh in May next year, and if Andy Flower makes RCB, it could be a challenge too.”Despite these concerns, Karthik has no doubts about Flower’s coaching credentials.“Is he good? Definitely. He is probably one of the best in the world, if not the best. Will he have time? That is the question. I would 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 has been a key figure in the franchise’s coaching set-up. While he is one of the main contenders to replace McCullum, Karthik believes that the demands of international cricket and franchise commitments make such a move difficult to foresee.
