Nigel Baker today called on his Haywards Heath team to find "that extra ten per cent" in their bid for Twickenham and league safety.

Heath aim to beat last year's club record breaking run in the EDF Intermediate Cup when they go to Dunstablians in the last eight tomorrow.

The tie gives Heath and their supporters a chance to make up for the near miss of last year, when they lost at home to Morley, and to forget their deteoriarating position in London One.

The distaction might have come at just the right time. Baker reckons his young side would have the league wins they needed if they had a touch more experience.

But he will hope their exuberance allows them to enjoy their trip to.

The Heath coach said: "We have got to step up that extra ten per cent if we want to start beating sides.

"I know how Dunstablians play and where some of their players are from.

"We don't think they have got anything special compared to the top teams in our league.

"They are not in the class of Worthing, Ealing or London Scottish.

"They are about our kind of level and it will be about who wants it more."

With Owen Ashton out injured, Heath will field, at most, three of the team who went out in the quarterfinals a year ago.

Current skipper Dave Wattam was not in the side and Glenn Rankin came off the bench meaning Tom Jordan could be only survivor from last year's starting line-up Although Heath scored very late to reach this stage of the Cup, they have lost close games in League One and are perched just above the drop zone.

Their six remaining league fixtures include games against the top three and they are having to keep a wary eye on the revival being staged at Portsmouth, who won at Whitemans Green recently.

Baker reckons two wins will keep Heath up which makes the home clash with Barnes and trips to Staines and Shelford particularly significant.

He added: "If I wasn't worried about our league position there would be a problem.

"We should have won our last three games but it is getting harder and harder.

"It comes down to lack of experience.

We don't have the ability to change gameplans to win games.

"I think we can beat any side in our division apart from maybe the top two.

"Two more wins in the league and we will be fine but we still need to go out and get them."

Dunstablians look to be in form.

They went second in Midlands One with a storming second-half display to win 43-29 at South Leicester last Saturday.

Heath are missing Sussex under-20s skipper Sam Pargetter, who has a knee injury, while fellow backs Sam Humphrey-Baker and Adam Phillips are also unavailable.

Their trip north means the Sussex Trophy quarter-final with East Grinstead has been put back to March 10.

Worthing, meanwhile, have been given a free ride into the semis after Brighton pulled out of their trip to Roundstone Lane.

Their decision did not please Worthing coach Ian Davies.

He said: "What's the point in having a cup competition if teams aren't willing to play.

"We've lost the chance for some players to have a game and the revenue we would have taken behind the bar."
