Saints enjoyed home advantage all the way through to the semi-finals in each of the last two years when they went on to lift the Cup.

It is more than three years since they were drawn away from home.

Warrington lost at Knowsley Road in the quarter-finals last season and host Saints in a Super League game at the Halliwell-Jones Stadium on Friday.

St Helens coach Daniel Anderson said: "Warrington will be no different to this week, they are a very dangerous team."

Wolves lost 30-22 away to Saints in the second round of Super League and go into Friday's game on the back of three successive league defeats.

"The next month is massive for us," said coach Paul Cullen. "It goes without saying, now is the time to hit form."

Quins lost to Leeds in the quarter-finals in 2006 and were hammered 48-0 in the league at Headingley this year.

But Rhinos coach Brian McClennan said: "We will be expecting a tough test down at Harlequins.

"Being drawn away to another Super League club is always one of the toughest draws, but we have got four games before then and will hopefully go there in good form."
