Something has got to give as Lancaster strikes back
When coach Stuart Lancaster needed a hand-up, Leinster held it out.
The 47 year-old took time out in the shadow of the 2015 Rugby World Cup, much of the abuse for England's failure placed on the head of the coach.
"It is a difficult position when you've lost your job as a national coach.
"I sat down to think, 'what's the next step?'"
There was time taken to travel and explore different environments, time to step back before moving forward.
Lancaster came to the conclusion that he wanted to return to his love of coaching rather than managing.
This is where Leinster came into it.
"They were the ones who had the confidence to ring me up and say, 'do you want to join us'?"
He used two pieces of advice given on to him by men working on the underside of the globe.
"One from Wayne Smith was, 'get back to doing what you love' which was coaching," he said.
"Wayne Bennett, who is the Australian rugby league coach said: 'wherever you go, make sure you 100pc want to go and they 100pc want you to come'. That's how it feels here and that's how why it works so well."
When Leinster needed a voice of experience, the Cumbrian spoke out.
Now, Lancaster has the chance to show English rugby what they are missing by taking out one of their two best clubs
The payback is always dressed-up in silverware.
"We're top of the PRO12. They're top of The Aviva. They've scored 70-odd tries this season and so have we.
"Something has got to give."
