NEW Saints coach Paul Wellens has explained why he cannot continue on England's coaching staff for the World Cup which starts this month.

Wellens, who was appointed Saints' head coach as a replacement for Kristian Woolf yesterday, has worked under Steve McNamara, Wayne Bennett and current England boss Shaun Wane.

However, he wants to be 100 per cent cent committed to his new role - something he says the England boss understood.

Wellens said: "The unfortunate part is that I have been involved with England for a number of years now and I was really excited about the opportunity to be involved in a World Cup, but I think the most important thing is that I'm committing to this role wholeheartedly, 100 per cent.

"I've been in dialogue with Shaun Wane about the possibility of this happening, he's been really good, very understanding of the situation.

"He is obviously someone who has coached his hometown team and understands the pressures that that brings - and I can't thank him enough really for his support in allowing me to take up this opportunity.

"I'm going to miss being involved, however I feel it was the right decision.

"We have another week with the staff looking at pre-season and how that will look for us.

I will get a break with the family - it is what I am looking forward to, to recharge the batteries - and as soon as I step off the plane when I get back I will be straight into it."

England Knights head coach Paul Anderson will join Wane's coaching staff ahead of the World Cup.

Wellens also said he believed Saints were "in discussions" over a possible World Club Challenge clash with Australian champions Penrith Panthers next year.

"Certainly from a coach and player perspective, it would be a fantastic opportunity to take on Penrith - what a team they are," Wellens said. "This team have earned an opportunity to take on that challenge."
