Liverpool literally scored all of them goals against Manchester United already (7-0) believe me they'll find it difficult to score against Fulham during the weekend fixtures. Fulham are also fighting hard for the spot of European Competition next season don't even expect them Fulham to slow down for Liverpool, no that wouldn't work.
If Liverpool wants to get back to good days then they have to go back to the signature of new players, Henderson, James Minler, Chamberlain, they all need to leave the club for youngins to come in. Tough test against Fulham I must say.
Fulham are hard to predict as they have surprised some of the big teams quite often this season. But what's the problem? Liverpool are playing at home and I think they can really be favorites to win the match. I agree it won't be easy, but Liverpool are the team most likely to pick up the 3 points at the end of the match.
So far Liverpool have only lost 1 at home in their 13 home matches, while Fulham have lost 6 of their 13 away match. From that I think you can determine who is the favorite even though in football nothing is certain.
