Veteran Leeds centre Keith Senior has revealed there was a "big divide" between the Rhinos players and their arch rivals from St Helens during England's disastrous World Cup campaign.

The Rugby Football League have yet to complete their review of the debacle in Australia but Senior, who has confirmed his retirement from the international game, admitted that players from the two Grand Final camps failed to hit it off together.

"It's just getting the cohesion and working together. I think in this World Cup we didn't work as a unit," said Senior. "There was a big divide - so many Saints players and so many Leeds players and we didn't gel on the field which was a big disappointment."

He added: "At the end of the day we didn't perform, we let ourselves down."

"There are a lots of ifs and buts about why we didn't perform. That's something the coaching staff have to look at.

"There's definitely the players there. We haven't as much strength in depth compared to Australia but we can definitely get a winning 17 out on the field."

Senior, who will turn 33 in April, has ruled himself out of the end-of-season Four Nations Series, following the lead set in recent years by St Helens duo Sean Long and Keiron Cunningham in concentrating solely on club rugby.

The former Sheffield Eagles three-quarter won 33 caps since making his Great Britain debut in 1996 and played 10 times for England, eight of them in the World Cup tournaments of 2000 and 2008.

"I've had a great international career but you have to think of your future," he said. "I want to play for as long as I can while the body is still feeling strong.

"And it's about time I started to pay a bit back to Leeds for showing faith in me. If it means a couple more years playing Super League, that's something I need to do."
