Mick Newell has admitted that it is a case of “now or never” if he is to become England coach.Newell, the longest serving head coach in first-class county cricket, will be interviewed for the England role sometime in the next couple of weeks and accepts that it will probably represent his final chance to gain the job he sees as “the ultimate.””It probably is a question of now or never for me,” Newell told ESPNcricinfo. “I’m 49 now and, by the time England look again, I can see them thinking I may be too old.”It’s likely to be at least three years before the chance comes around again, isn’t it? I haven’t been told when the interviews will take place yet, but yes, I have been asked for an interview and I expect it will be in the next week or two. Maybe even the end of this week.”Newell has been with Nottinghamshire for 30 years, first as a player and then as a coach, and assumed the head coach role in 2002. The club has subsequently won the County Championship twice – in 2005 and 2010 – and won the YB40 trophy in 2013. He has previously been linked to the Bangladesh coaching role but withdrew, citing the difficulty of spending time away from his children.”I have a great job here at Nottinghamshire,” he said. “But the England role is the ultimate for an English coach. I’m sure any coach will tell you they would love to work with the very best players their country has to offer.”Newell is on a short-list for the England role that also includes the Lancashire coach, Peter Moores, the Sussex coach, Mark Robinson, the England limited-overs coach, Ashley Giles and the New South Wales and Kolkata Knight Riders’ coach, Trevor Bayliss. While Giles was the favourite for the role, England’s World T20 defeat at the hands of Holland has damaged his chances and there appears to be an increasing chance that Moores could take the position with Robinson as his deputy.
