GIANTS coach Jon Sharp has issued a big thank you to the fans ahead of the semi-final.

Up to 4,000 are expected to travel over to Warrington, with those without tickets able to pay on the day.

And Sharp, pictured, knows they have a vital role to play tomorrow.

"We had around 2,000 fans at Wakefield and they gave us a huge lift in a very close game," said Sharp.

"Their contribution was vital, and I know they will be right behind us tomorrow. For that, I would like to thank them in advance."
