ALL eyes will be on Bramall Lane on Tuesday night as Wanderers wait to see who they will meet in the quarter-finals of the FA Cup.

Arsenal remain favourites but Sheffield United's prospects have improved with Arsene Wenger's replay plans being ravaged by injury and suspension.

Blades manager Neil Warnock has dismissed suggestions that the Gunners have been weakened to the point of vulnerability but he must have been encouraged by news that top scorer, Thierry Henry, has joined the list of missing stars.

Henry is out with an Achilles injury and is joined on the treatment table by Robert Pires, Sol Campbell, Edu and Gilberto Silva, while suspension rules out Dennis Bergkamp, Jose Antonio Reyes and Robin van Persie.

It means Wenger will field a makeshift strikeforce of Freddie Ljungberg and either 18-year-old Quincy Owusu-Abeyie or 17-year-old Arturo Lupoli, seemingly giving the Blades the perfect opportunity to book a trip to the Reebok on the weekend of March 12 and 13.

Warnock, though, feels his side's chance passed them by at Highbury 10 days ago when a last-minute Andy Gray penalty gave them a battling 1-1 draw against the Premiership champions.

"They've got international players throughout, so it doesn't matter what team they put out," he said.

"People have been writing them off of late, but apart from the Champions League game in Munich, I think they have been playing quite well.

"Understandably, the pressure is on them to win every game and if they don't do then that prompts headlines such as 'they've gone'.

"But the element of surprise has gone for me, which I felt we had when we went down there, and because of that it will be 10 times harder to beat them on this occasion.

"The best thing is they know they will be in for a game, and that's a compliment for us because I think everyone knows we can give a good account of ourselves and that we will be organised and we will break when we can.

"But I think they will come to try and beat us at football because technically they are better than us."

Blades captain Chris Morgan, who returns after missing the initial tie through suspension, says Warnock's warriors have taken a leaf out of Sir Alex Ferguson's book and will again set out to knock Arsenal out of their stride, as they did at Highbury.

"When Manchester United have played Arsenal they have showed you can unsettle them," Morgan said.

"I'm not talking about physically doing them, but when you play Arsenal you have to get in their faces and close them down.

"So we went into the game down there and said to ourselves 'let's get into them, get into their faces and close them down and see how they react', and it will be the same for tonight."

Warnock is without the suspended Danny Cullip - the man at the centre of the flare-up that resulted in Bergkamp being red-carded and Reyes receiving a retrospective ban - and goalkeeper Paddy Kenny is doubtful with a hip injury.

But Paul Thirlwel returns from suspension and Nick Montgomery, Derek Geary and Andy Liddell are also available after being rested at the weekend.

Should Arsenal get through, Bergkamp, Reyes and van Persie will all be eligible to play against Wanderers but Pires will still be sidelined and Campbell, Gilberto, Edu and Henry could all be struggling.
