CAUTIOUS Giants coach Jon Sharp has warned his players to take no notice of Harlequins' early-season form.
The former London Broncos have already suffered two shock home defeats in their opening five Super League XI fixtures.
They were beaten 26-6 by Wakefield three weeks ago and then lost 34-20 to Castleford Tigers.
It's been a different story on the road, however.
Only a controversial penalty denied them an 18-16 victory at champions Bradford Bulls. The game finished at 18-18.
Then a fortnight ago, they produced a superb defensive effort to beat Hull FC 10-6 at the KC Stadium.
And Sharp knows this strong away form makes them a very dangerous side.
"Harlequins are a massive threat," said Sharp.
"They are a quality team with superb individual players who are capable of causing any side in Super League lots of problems.
"And the nature of their home defeat to Castleford makes them even more dangerous.
"When a side like this has their backs against the wall, that's when they are at their most lethal.
"There won't be many teams in the competition this year that will win at Hull and draw at Bradford.
"This is the Harlequins side we are preparing to face on Sunday - a side that are coming to challenge us all over the park."
Harlequins' attack will once again be spearheaded by inspirational kiwi scrum half Thomas Leuluai, pictured right, who was one of the Broncos' main men last season.
His impressive half-back partnership with Luke Dorn could prove the biggest threat to the Giants on Sunday, particularly if they are handed quality service from their big pack.
They are, however, still lacking the services of strike centre and goalkicker Paul Sykes, who is recovering from a serious kidney injury suffered at Hull.
Also on the sidelines is England international Rob Purdham, who picked up a heavy shoulder knock against Castleford.
"They do have a couple of key players ruled out, but their squad still looks very strong," said Sharp.
"But although we've taken a very good look at Harlequins, this Sunday really is all about us.
"The key this weekend is how we perform on the back of St Helens last week.
"We've put on two big shows at the Galpharm this season.
"Let's make it three on Sunday!"
