The match kicks off a run of three games in a week for the Reds, with a trip to Wigan to come in midweek followed by a home clash with Chelsea which could go some way to deciding the outcome of the Barclays Premier League title race.

Liverpool conceded a late equaliser to draw 1-1 with Everton in the league on Monday, a result which denied them the chance to replace Manchester United at the top of the table.

And Benitez will now consider resting players this weekend in a bid to stop the team from surrendering further ground.

"We will see. We have plenty of time before the game but we have to think about Wigan and Chelsea. Anyway, I think we have enough quality in the squad," he told the club's official website.

One player likely to be involved, though, is Spain striker Fernando Torres, who has so far suffered an injury-interrupted season.

"I was impressed with him on Monday. It is not easy to play in a derby when it is so intense. He was exhausted at the end but he did well," Benitez added.

"He is very close to full fitness - now it's just about getting match fitness. He needs to play games.

"You know a striker needs to play games and be in front of the goal a few times. Hopefully he can score this weekend."

Manchester United, still fighting for trophies on four fronts, take on Tottenham on Saturday, and Spurs boss Harry Redknapp intends to send out a "mish-mash team".

Redknapp saw his side taken to extra-time by Burnley in the Carling Cup last night and avoiding relegation from the Premier League remains his priority.

"The games against United really is so secondary to me now," Redknapp told Sky Sports.

"If Sir Alex Ferguson is listening, I'm really going to send a real mish-mash team up there. I hope it doesn't upset the supporters, but we played extra-time and we're out on our feet a little bit."

Arsenal will look to keep their last realistic chance of a domestic trophy alive when they travel to last season's losing finalists Cardiff on Sunday.

Arsene Wenger's men are six points off the pace in the league, and struggling to keep themselves inside the top four, but will have their work cut out against a Cardiff side in contention for promotion from the Coca-Cola Championship.

The fourth round gets under way tomorrow night with a mouth-watering East Midlands clash as Derby, now managed by Nigel Clough, welcome the club where his father Brian enjoyed such success, Nottingham Forest.

On Saturday, last season's winners Portsmouth host Swansea, Chelsea take on Ipswich, Torquay face Coventry and Kettering, the lowest-ranked team left in the competition, welcome Fulham.

Champions League chasing Aston Villa travel to Doncaster, Hartlepool take on West Ham, Hull tackle Millwall, Sheffield United welcome Championship basement boys Charlton and Sunderland host Blackburn.

The other three ties see Watford face Crystal Palace, West Brom challenge Burnley and Middlesbrough visit Wolves.
