YMCA coach Carl Thewlis is calling for a major improvement from his backs in tomorrow's big derby clash at Old Brodleians (2.15).

"I was disappointed with our threequarters against Hoylake last week," admitted Thewlis.

"They need to be far more decisive and make some changes very soon, or I'm going to be forced to make some changes myself.

"It's another massive game for us tomorrow, because if we lose we can be right back down there with the relegation contenders."

The coach and selectors are looking to name a virtual full-strength squad, which will be further enhanced by the addition of new recruit Damian Pearson, who has arrived from West Leeds.

A big second rower, Pearson has been training for the last couple of weeks and is keen to make his first-team debut.

Thewlis has Simon Wilson again at scrum half for the clash at Hipperholme, meaning Neil Walker will now return to his customary spot at No8.

The Calderdale side are bottom of the division with seven points from their 11 games, and the worst defensive record in Yorkshire I (248 points against), but as Thewlis is quick to point out: "Anyone can beat anyone else in this division this season, as has already been proved by recent results."

Ex-Huddersfield Giants player Jamie Bloem is on the bench for Brodleians, but they will include Kenyan second rower John Wanderi, who is one of their formidable pack men.

YMCA gained first blood last month when they defeated Brods 31-12 at Salendine Nook with tries from Stuart Morton, Dave Holmes, James Bracken and Neil Walker.
