Alvaro Arbeloa accepts overhauling Premiership leaders Manchester United is a long shot for Liverpool.

"The challenge to win the league is not lost, but every time it is getting more difficult for us. To give so many points to Manchester United and we still have to play at Old Trafford is very dangerous.

"We are not going to give in and will continue to challenge until the very last moment.

"Manchester United are not showing any weaknesses and we all thought there would come a time where they would slip up, but that has not happened," admitted the Spanish fullback.
