Leeds coach Brian McClennan has identified Australian hooker Chad Randall as the main danger to his side in tonight's tricky fixture with Harlequins at the Twickenham Stoop.

Randall, who will make his 98th consecutive appearance for the Londoners, was a tryscorer in their shock 21-4 win at Headingley in April and was also on the mark on his 100th appearance for the club in last week's 40-10 win at Hull KR.

"Chad Randall is a quality player who gives very good service to his team out of dummy-half," said McClennan.

"He has a high workrate in the middle zone and the team play off the back of him. He gets them rolling forward and he is very smart and someone we will really need to keep an eye on on Saturday night.

"But they have quality throughout their side as well with guys like Danny Orr and Rob Purdham plus Ben Kaye, Luke Gale and Danny Ward, who have connections to the Rhinos and who I am sure will be up for a big game against their old team-mates."
