It will be master against apprentice when Wales do battle with France in their must-win European Championship clash in Albi on Saturday afternoon.
The second round of matches pits French head coach and former Hull FC and Wakefield head coach Richard Agar against his old mentor John Kear, a former England and France boss who is now in charge of his third national team after succeeding Iestyn Harris at Wales.
The 2014 European Championship is one long round of reunions for the veteran former Wakefield Head Coach Kear, who helped launch Agar's coaching career at Hull in 2004, coached Scotland captain Danny Brough at two Super League clubs and in tandem with Ireland boss Mark Aston steered Sheffield Eagles to their stunning win over Wigan in the 1998 Challenge Cup final at Wembley.
"I go back a long way with all three," Kear said. "I've had a very interesting last 10 or 15 years. We keep inter-twining, locking horns and it's great. It's part of the rugby league family."
Both France and Wales go into their meeting on the back of defeats and know a loss in Albi will end their hopes both of tournament success and of securing the big prize of a place in the 2016 Four Nations Series.
Kear's men will be looking to bounce back from their 42-18 defeat by Scotland while pre-tournament favourites France are reeling from a shock 22-12 loss to Ireland.
"We had a really good review of the previous performance against Scotland and we've identified areas that we need to tidy up and improve on," Kear said.
"The players' application has been first class and if they take that on to the field against France then I'll be very satisfied.
"This week will be vastly different to the Scotland game in Cumbria last Friday. We played in a howling gale and driving rain and, from the forecasts we've been getting, we'll have no rain on Saturday, 25 degree sunshine and the ground will be very firm."
Agar is poised to give a debut to Lezignan hooker John Boudebza, who this week completed a move to Hull KR, while Kear has called up four fresh faces as he rebuilds a youthful Welsh squad.
"It's exciting for the game in Wales," Kear said. "We've given a lot of people some opportunities. Some have taken them without a shadow of a doubt and are going to be here for a good few years yet."
For Wales and Ireland, who host the Scots in Dublin on Saturday afternoon, there is also the prospect of securing automatic entry into the 2017 World Cup down under.
"With the enormity of this fixture we will be looking to up our game against Scotland," Aston said. "Last week was a fantastic victory and it is important that we keep the spirit that we showed against France and build on that."
Scotland coach Steve McCormack, who celebrated 10 years in the job on Friday, reckons his side will need to find some improvement if they are to halt the improving Irish.
"A lot of people were shocked by Ireland beating France but nothing surprises me any more," said McCormack.
"We know we are going to have to be at our very best to win.
"If we play like we did in the second half against Wales we will give ourselves a chance but we've got to learn from where we went wrong in the first half."
