GIANTS coach Jon Sharp today issued a major warning to his players as they prepare to face York City Knights in Sunday's big Challenge Cup quarter-final clash at the McAlpine (3.00).

His Super League side go into the weekend showdown as red-hot favourites to beat their National League II opponents and reach the last four for the first time in 33 years.

And to make that happen Sharp is demanding a similar performance to that produced against Bradford Bulls last weekend - or suffer the consequences!

"They set the standard against the world champions on Sunday, and all the players know I don't expect that standard to dip," declared Sharp.

"That's something I simply won't tolerate.

"From day one I've been calling for consistency in this team, so that means going out against York on Sunday and playing at least as well as they did against the Bulls.

"The players know how I feel, and they also know how I will feel if they let their standards slip.

"This is a massive game for this club and it obviously demands a massive performance from everyone.

"We all want to get to the semi-finals and we all know what is required to make that happen."

Sharp is boosted by the fact he is virtually picking from full strength.

Apart from long-term injury victim Paul White, who suffered a broken leg in the pre-season win over Castleford, every member of the Super League squad is available for selection.

And Sharp has hinted he may make changes from the side that did so well against the Bulls.

"Obviously, Jim Gannon comes back into the forwards' equation," added Sharp.

"But the key to who I choose depends a lot on what the opposition may have to offer. Luckily, I'm not short on options."
