GIANTS coach Jon Sharp has warned his players that only their very best will be good enough against holders St Helens in Sunday's big Powergen Challenge Cup fourth-round clash at the Galpharm (3.00).
Sharp's side go into this weekend's Cup showdown on the back of convincing Easter Super League victories over Wakefield and Salford.
That's put the injury-free Giants in positive mood ahead of this Sunday's top tie.
But Sharp knows his side need to produce a massive improvement if they are to claim the scalp of his former club and make further Cup progress.
"If we are to do anything against St Helens, everyone from one to 17 has got to produce their best game of the season," said Sharp, who spent two seasons as assistant to Saints boss Ian Millward at Knowsley Road.
"We've been showing signs of improvement throughout the season, and we can't afford to see that pattern change this weekend.
"Fortunately, the squad is full of confidence right now and really looking forward to giving it their best.
"We showed at Saints last month that we can compete with them, and had it not been for a poor start we could easily have beaten them.
"It's something that the players are all well aware of and that's added to the positive feeling that's flowing through the squad."
Sharp has revealed he is facing a massive selection headache this weekend, with everyone staking a claim to play in the last-32 tie.
But he admits that at this stage he is keeping his cards very close to his chest.
"There will be a late call on selection, but I am looking at making some slight tactical switches," he added.
"That's something you always need to look to do, especially against a side like St Helens.
"This game has all the makings of a classic."
St Helens are also expected to field a virtual full-strength side, with Paul Sculthorpe (hamstring), Jason Hooper (knee) and Willie Talua (leg) in line to return.
Huddersfield officials are confident of attracting a big crowd this weekend, with St Helens expecting to bring around 3,000 fans.
To avoid congestion on the day, the advice is to buy tickets in advance from the Giants' Galpharm office. It is open until 5pm today and tomorrow from 9am-noon.
