Warren Gatland has backed Andy Farrell to be the next British and Irish Lions head coach after ruling himself out of the running for the 2025 tour of Australia.

New Zealander Gatland, who late last year returned for a second spell as Wales boss, has overseen the last three Lions tours.

Farrell was on Sunday named World Rugby coach of the year after leading Ireland to a Guinness Six Nations Grand Slam amid a 17-match winning run.

“A few weeks ago, I was asked by Nigel Walker, Wales’ director of rugby, if I was interested in putting my name forward to be head coach for the next tour in Australia in 2025,” Gatland wrote in his column for the Telegraph.

“It did not take long to get back to him.

“I told him I was not going to put my name forward. I told Nigel that I would have no problem if any of my support staff were to be asked to be involved as I would see it as a great experience for them.

“But I think it is the opportunity now for someone else to be head coach and Andy Farrell would have my backing for the job.

“You cannot deny what Ireland have achieved as a nation over the last few years. There is no doubt that Andy has done a fantastic job.”

Gatland led the Lions to a 2-1 win in Australia in 2013, a drawn series in New Zealand in 2017 and a 2-1 defeat in South Africa in 2021.

Farrell was part of the 60-year-old’s coaching staff for the first two of those three tours.

The 48-year-old Englishman’s stock has risen significantly over the past couple of years, albeit Ireland suffered a quarter-final exit at the Rugby World Cup in France following a 28-24 defeat to runners-up New Zealand.

Gatland, who also assisted Sir Ian McGeechan on the 2009 Lions tour of South Africa, offered to support his successor in an advisory capacity.

“If the next head coach wants to tap into my experiences from the last four tours, then I would still love to be involved in some way by passing on the knowledge and experience I have gained in trying to create harmony within a group of players from different backgrounds,” he continued.

“For the Lions, it is the least I can do.”
