Liverpool goalkeeper Pepe Reina admits Manchester United will always be ahead of them because of their spending power.

He said: "If they beat us or we draw it will be very difficult.

"They have spent a lot of money in the last three or four years. It makes a big difference when you spend more than £100million.

"It makes you even stronger than you already are. Carlos Tevez is a big price, Wayne Rooney is big money, Cristiano Ronaldo, Dimitar Berbatov etc.

"To compete with that is almost impossible. To face this kind of team with the power in attack and the players of this quality, it is always difficult to defend.

"They have a really strong squad and they can use different players. It is tough."
