British and Irish Lions coach Warren Gatland has named Andy Farrell, Rob Howley and Steve Borthwick as his three assistants for next year's tour of New Zealand and left the door open for a surprise call-up for former Fiji Sevens coach Ben Ryan.
Former dual-code international Farrell, England's defence coach under Stuart Lancaster and now doing that job for Ireland, will fill the role again for the Lions having done it under Gatland during the series victory over Australia in 2013.
Howley, currently leading Wales during Gatland's sabbatical, will again be the backs coach. Borthwick, currently working under Eddie Jones as forwards coach for England, will look after the forwards and bring his lineout expertise to the Lions.
"I said from the outset it was important to have continuity because we need to hit the ground running, given the limited preparation time," Gatland told a news conference near Dublin as he announced his coaching lineup.
"In Rob and Andy we have guys who understand the Lions concept, have worked together and know how to coach a winning Lions team. It's also important to have some new input.
"Steve has done a great job in shaping the England pack and played a major role in their recent run of success, so I'm looking forward to working with him."
Gatland confirmed he was also considering an extra specialist coach after media reports suggested Ryan, the Englishman who led Fiji to Olympic gold in Rugby Sevens at this year's Rio de Janeiro Games, could be included.
Ryan spent six years as England Sevens coach before taking over Fiji and transforming them from a side of brilliant but erratic performances into the dominant force in the Sevens game, culminating in their Rio triumph when they beat Britain in the final to win their country's first ever Olympic medal.
Ryan stood down from the role after the Olympics and is currently working as a consultant.
"I think over the next couple of months I want to add some specialist people in the coaching set-up," New Zealander Gatland said.
"There's no rush, it's just a case of making sure I speak to the right people."
Gatland, however, declined to confirm that Ryan was among them and laughed off some of the speculation.
"Some of the names have been fantastic," he said.
"I haven't heard of some of them."
The Lions will tour New Zealand next June and July, playing three tests and seeking only their second series win in the country after their 1971 triumph.
They were hammered 3-0 in their last tour their in 2005 under Clive Woodward.
Meanwhile Robin McBryde will be in charge of the Wales team for next year's tour of the Pacific Islands.
McBryde replaces interim head coach Howley, who has joined the British and Irish Lions coaching team for the 2017 New Zealand tour.
McBryde will lead Wales for the third time, having been in charge for the tour of the United States and Canada in 2009 and a two-test campaign against Japan in 2013, with those trips coinciding with Lions appointments for Gatland and Howley.
Welsh Rugby chief Martyn Phillips said that the governing body was in advanced talks with a number of other coaches and hoped to confirm the full management team for the tour next week.
The tour begins in June, with fixtures against Tonga and Samoa to be confirmed.
