Warren Gatland has added Graham Rowntree and Neil Jenkins to his Lions coaching team for the tour of New Zealand this summer.

Both men served on the staff of the unsuccessful 2009 tour in South Africa and the winning 2013 team four years later in Australia, when Gatland was head coach last time.

Rowntree and Jenkins have been on four Lions tours between them as players and join Gatland’s three assistants of Steve Borthwick, Andy Farrell and Rob Howley, who were announced in December of last year.

Lions starting XV - Six Nations round four Show all 15 1 /15 Lions starting XV - Six Nations round four Lions starting XV - Six Nations round four 15. Leigh Halfpenny (Wales) The man of the series from four years ago powers his way back into the side at the expense of Stuart Hogg for the first time this championship. The Scotland full-back was unable to show his best as a concussion forced him off the field after 17 minutes against England, but Halfpenny was at his best to help guide Wales to victory against Ireland on Friday, setting up George North for his first try and landing three out of four kicks at goal. Getty Lions starting XV - Six Nations round four 14. George North (Wales) Speaking of North, the towering wing returned to form to bag two tries against Ireland and inspire Wales back to victory. His exploits Down Under were well-documented in 2013, and he is the one wing that the British Isles can boast who is undoubtedly more physical that what New Zealand have to offer. Getty Lions starting XV - Six Nations round four 13. Jonathan Joseph (England) Three tries from the Bath outside centre puts him back into Warren Gatland’s thoughts, and if he can produce the type of performance that he did against Scotland on a regular basis, he’d be one of the first names on the team sheet. Getty Lions starting XV - Six Nations round four 12. Owen Farrell (England) Put his blip against Italy behind him to return to his meticulous ways against Scotland, converting 11 out of 12 kicks and unlocking the flowing potential outside him to help Joseph and Anthony Watson to tries. A dependable pair of hands who also adds cover to the fly-half position and takes the pressure off the 10. Getty Lions starting XV - Six Nations round four 11. Liam Williams (Wales) Having shown his attacking potential over the first three rounds of the Six Nations, it was his defensive qualities that shone through in the win over Ireland. Negated the threat of Keith Earls and ensured that Wales’s try line remained intact come full-time. Getty Lions starting XV - Six Nations round four 10. Johnny Sexton (Ireland) Even in defeat, Sexton was able to prove his worth to Ireland’s cause, given that Ireland conceded 10 points without him. He sparked the side back into life, giving them a sense of direction and the creativity in attack that will test the All Blacks through a variety of back-line move and enormous up-and-under kicks that gives the likes of North and Williams the chance to compete for the high ball. Getty Lions starting XV - Six Nations round four 9. Rhys Webb (Wales) It was the Welshman who came out on top in the battle of the Lions hopefuls, given that Conor Murray saw his match ended prematurely through an arm injury. Webb didn’t have it all his way, but his pass to Halfpenny that set-up North’s try was sublime and he also spotted the gap to send the win over for his second. He’s quickly becoming the most attacking scrum-half in the world. Getty Lions starting XV - Six Nations round four 1. Mako Vunipola (England) Another solid appearance under his belt, Vunipola is regaining his full fitness week by week and helped England keep their foot on the gas when he came on for Joe Marler on Saturday. He offers skills in the loose that no other prop in the northern hemisphere can do, and for that he needs to start against the All Blacks if the Lions are to find ways of breaking down their defence. Getty Lions starting XV - Six Nations round four 2. Ken Owens (Wales) Has gone under the radar somewhat, but while questions remain over Dylan Hartley’s form and Rory Best’s decision making, Owens is simply doing the basics well. His lineout throwing is first class, and with plenty of his jumping options in the pack, it makes sense for him to start the first Test. Getty Lions starting XV - Six Nations round four 3. Tadhg Furlong (Ireland) With Dan Cole continuing to push his claims, Furlong is under pressure to retain the shirt and just about held onto it this weekend despite an underwhelming performance in the scrum battle, where Ireland did not hold the advantage that many thought they would. Needs a big performance against England to convince Gatland’s he’s his go-to tighthead. Getty Lions starting XV - Six Nations round four 4. Joe Launchbury (England) His excellent championship continued with a brilliant display against Scotland both with and without the ball. Is building the perfect case of why seizing your opportunity is so important, and is now well in the Lions reckoning. Getty Lions starting XV - Six Nations round four 5. Alun Wyn Jones (Wales) Back in the side after an impressive showing, both in the second row and as Wales captain. He got all the important decisions right, and looked like the man who skippered the Lions to victory in that crucial third Test against Australia. He was a nuisance in the lineout for Ireland and destructive in defence. Getty Lions starting XV - Six Nations round four 6. Sam Warburton (Wales) A dominant display put the Irish back-row in the shade in Cardiff as the 2013 tour captain proved why he is a must for the Test side, and put Maro Itoje’s starting spot in major doubt in the process. He could yet end up captaining the Test side once again if Gatland decides he’s rediscovered his best form. Getty Lions starting XV - Six Nations round four 7. Justin Tipuric (Wales) The most natural openside that is certain to be in the squad, Tipuric offers a physical presence over the breakdown, a turn of pace rarely seen in forwards and an alternative lineout option. Getty Lions starting XV - Six Nations round four 8. Billy Vunipola (England) The younger of the Vunipola brothers made his return on Saturday and immediately proved why he is being put on a world class level. He scored a try within minutes of coming on and went about imposing himself on the Scottish defensive line. It was good to see him back and in plenty of time to prove his fitness for the Lions tour.

Gatland said: “We all know what Neil and Graham bring - a huge amount of knowledge, experience and expertise at club [level], international [level] and eight Lions Tours between them. They understand what it will take to win in New Zealand and to have them on board again is positive.

“I know Graham and Steve will complement each other and Neil will give us valuable backs and skills support.

“Given the schedule, with two games a week, having six coaches will allow us to devote enough time to ensuring we are successful.”

Rowntree, who was sacked as England forwards coach following Eddie Jones’ appointment after the disappointing World Cup in 2015, has been working with Harlequins and said he was grateful for the chance to go on tour again.

“I am honoured to be asked to tour with the British and Irish Lions again and I really am thankful to Harlequins, John Kingston and David Ellis for allowing me to go,” he said.

“Having experienced the highs and the lows of the Lions as a player and a coach, I know how special it is.

“This year will be the ultimate challenge considering the form that New Zealand have been in across the last decade, but looking at the talent and potential in England, Ireland, Scotland and Wales, it is a hugely exciting opportunity for us to do something incredible.

“I am grateful and excited for the opportunity ahead, but my attention will firmly remain on Harlequins until the conclusion of our season.”
