Blues start the 2014-15 league season at Nottingham.
He's the man who's masterminded Northampton Saints' rise to the top, but what's the secret to Jim Mallinder's success?
Northampton Saints are back in domestic action this weekend, a week on from their historic European win over Leinster.
Northampton Saints winger George North has been named in the Wales side for this weekend's opening autumn international against South Africa.
The 21-year-old has been a regular in the welsh line-up since making his debut in 2010, and performed a starring role in this summer's Lions series.
North will take up his usual position on the wing, with debutant Eli Walker also part of the back three.
Wales team to face South Africa:
Leigh Halfpenny (Cardiff Blues), George North (Northampton Saints), Jonathan Davies (Scarlets), Scott Williams (Scarlets), Eli Walker (Ospreys), Rhys Priestland (Scarlets), Mike Phillips (Unattached).
Gethin Jenkins (Cardiff Blues), Richard Hibbard (Ospreys), Adam Jones (Ospreys), Bradley Davies (Cardiff Blues), Alun Wyn Jones (Ospreys), Dan Lydiate (Racing Metro), Sam Warburton (Cardiff Blues, captain), Toby Faletau (Newport Gwent Dragons)
Northampton Saints director of rugby Jim Mallinder says that he is "delighted" for his England stars, despite them being unavailable for selection for the next few weeks of the Aviva Premiership campaign.
Courtney Lawes, Tom Wood and Lee Dickson have all been named in England's starting line-up for Saturday's clash against Australia at Twickenham, whilst Dylan Hartley and Ben Foden are amongst the replacements.
As a result, the quintet will all be missing for Northampton's trip to London Irish on Sunday as the Saints look to maintain their impressive start to the season.
Northampton Saints stars Lee Dickson, Courtney Lawes and Tom Wood have all been named in England's starting line-up for Saturday's crunch clash with Australia at Twickenham.

Lee Dickson has been preferred at scrum-half to Leicester Tigers' Ben Youngs.
Meanwhile, Northampton captain Dylan Hartley will have to settle for a place on the bench after Tom Youngs was named at hooker.
Ben Foden has also been selected as one of the replacements.

Northampton Saints players Ben Foden and Lee Dickson joined teammates and other sport stars to support the local charity 'Niamh's Next Step'. The event, at Whittlebury Hall near Silverstone, was to raise funds for research into the brain disease neuroblastoma. See Donovan Blake's report.
Northampton Saints flanker Tom Wood has been named in the England matchday squad for Saturday's test against Australia.
