Leeds's gaze doesn't go beyond first minute at Hull – McClennan

"It's a tough draw," conceded Leeds coach Brian McClennan. "We'll have to perform very well to beat Hull on their ground."

McClennan, whose side lost 22-18 to St Helens in round four last season, hopes his side do not come unstuck at the KC Stadium this time around.

"It's part of the drama of the Challenge Cup that there are some tight encounters and exciting draws, he said.

"We'll take it one game at a time and that's all you can do. It's one hell of a challenge, going to Hull and playing them at their ground.

"We won't be looking any further than the first minute of that game and making sure we're in there competing and putting in a good performance and if we don't we'll be out."

The Hull-Leeds tie, which is also a repeat of the 1910 final which was won by Leeds, is one of four all-Super League ties.

Last year's runners-up Huddersfield Giants are at home to Hull KR, Wakefield Trinity Wildcats visit Harlequins and Catalans Dragons host Salford Reds.

Holders Warrington will begin their defence of the Cup against Championship club Featherstone Rovers.

The Wolves, who beat Huddersfield 25-16 at Wembley last August, will have home advantage in the fourth round on the weekend of April 16-18.

Wolves coach Tony Smith, who took less than six months to end Warrington's 25-year wait for a major trophy when they beat Huddersfield at Wembley, said: "That's a tough draw, tougher than most people would think.

"They are one of the favourites from the division below so it will be a tough fixture for us."

Smith admitted last year's triumph should provide the necessary motivation for them to make a similar push in this season's competition.

He added: "The will to go back and do it again is great from all of us. For the fans, players and coaches, that would be fantastic.

"It's a new year and you have to start all over again. Just by having the experience doesn't necessarily mean you are going to go back there again.

"It gives you a taste of what it's like and Wembley is certainly a special place. We'll be fighting to go back again."

St Helens, who won the trophy four times in a row up to 2008, are at home to Championship club Toulouse, one of four French clubs in the last 32.

"It's fair to say it's a favourable draw," said Saints full-back Paul Wellens.

Leigh must travel to Limoux while Widnes will be at home to Lezignan providing they overcome amateurs Wigan St Judes in a delayed third-round tie tonight.

The only amateur club definitely in the fourth round, Siddal, have landed a home tie against Batley Bulldogs.

Siddal, third in the National Conference League, earned their place in the draw when they beat struggling Championship One side Doncaster 26-0 in the third round.
