Wales coach Shaun Edwards has praised Newport Gwent Dragons after their bright start to the season under new boss Lyn Jones.
The Dragons currently sit fourth in the RaboDirect Pro12 table after two wins in their first three matches, defeating Ulster and the Scarlets at home.
A dismal defensive record in 2012-2013 saw the Dragons concede 589 points, at an average of 27 points a game.
However Edwards has noted the improvements in their defence under Jones so far this season, highlighting his experience of building quality defensive systems before with the Ospreys and London Welsh.
Edwards himself was linked with a move on Thursday to join Cardiff Blues on a part-time basis as a defence coach.
"The Dragons will be tough this season and it's good to see. Lyn's goal will be that no side coming up against them will have an easy time," Edwards told the South Wales Argus.
"When we won the Grand Slam in 2008 a lot was made of the defence but most of those guys were very well coached before they came to me.
"We had a lot of Ospreys in the team and what they achieved with Wales is an indictment of the work that people like Lyn had put in and what a quality coach he is.
"It's no surprise that the Dragons are improving, I thought that they would as soon as I saw Lyn come in.
"Every team that he has coached has had something about them, just look at London Welsh last season when they nearly pulled off a miracle by staying in the Aviva Premiership.
"I've got a lot of respect for Lyn and I like the way he goes about things. He says things as they are and there has been an improvement wherever he has been."
