Steve Clarke believes every one of the 11 players selected to face Manchester United on Saturday will have to be at their best if Liverpool are to bring three points back to Merseyside.

The Reds head to Old Trafford looking for a second win over Alex Ferguson's men in as many weeks.

But Clarke insists there will be no psychological advantage for the visitors despite their FA Cup triumph.

"We managed to beat them in the cup tie but I don't think that's got any bearing on this game," the first-team coach told Liverpoolfc.tv. "Every game in football is different.

"When you play against the teams who are in or around the top of the league, you know everyone has to put in a good performance and that everyone has to be at 100 per cent.

"It's a big game but it's no different to any of the other big games we've played this season, and in those we've done quite well. In the big games we've played and competed well, passed the ball well and created a lot of chances.

"We don't go there with any fear. We go there, like any game, trying to win and with a positive attitude."

Clarke was assistant manager at Chelsea during the Mourinho years, when the Stamford Bridge outfit were United's closest rivals for the title.

He hopes the same will soon be true of Liverpool.

"When I was at Chelsea we had some great battles with them," said Clarke.

"Chelsea and Manchester United have dominated the top two positions in the Premier League for the last seven years, so it would be nice to get Liverpool in the same position where it's ourselves and Manchester United who are battling for the title."
