With Wales coach Warren Gatland set to reach a century of Test matches next weekend, hooker Ken Owens claims his boss does not get enough credit.
Not only has Gatland led Wales to three Six Nations titles - including two Grand Slams - he has also been successful as coach of the British and Irish Lions.
Wales also reached a World Cup semi-final in 2011, under Gatland, while his travels with the Lions has seen them beat Australia and draw with two-time World Champions New Zealand.
As Wales supremo, he will rack up his 100th Test next Saturday in Dublin, when his current team face his former side Ireland.
And Owens said of the 54-year-old New Zealander: "He is a great coach, and his work with the Lions has put him up there with the best.
"Both inside and outside of Wales, for some reason, he's always had to prove himself, despite helping transform Wales.
"We've been right up in the mix and things haven't gone right always, but we've always been there or thereabouts, and we are a very tough team to break down.
"We have won three (Six Nations) championships and two Grand Slams, during the last 10 years, and he has won one Lions series and drawn the other.
"The New Zealand tour was the second-best result there in Lions history, and if you look at New Zealand over the past 20 or 30 years, they haven't lost at Eden Park and we got a draw there.
"They hadn't lost a home Test since 2008 or 2009, and we beat them in Wellington.
"He has been my only coach in international rugby. He knows how to get the best out of players.
"When we have been in tough situations, he knows how to get that extra couple of per cent out of you.
"He is a very good man manager. He has managed that and put a massive emphasis on the fact family comes first.
"If everything is fine off the field, then all you have to worry about is the rugby, and he's great at that."
