LUCAS today claimed Liverpool will enjoy a fruitful Christmas and prosperous New Year - provided they can floor Arsenal in the weekend's battle of the giants.[LNB]Though the Reds have endured one of the worst runs of form in their recent history in the past two months, they are still only three points off a place in the top four.[LNB]And with games against Wigan Athletic, Portsmouth and Wolves following Arsenal's visit, Liverpool have a chance to claw back lost ground going into the festive period.[LNB]Should they take maximum points in those fixtures, the picture will change dramatically going into 2010 which is why Sunday's clash at Anfield has assumed huge significance.[LNB]That's why Lucas believes it is vital players give the club a much-needed lift by beating one of their biggest rivals and making a statement of intent.[LNB]'This is a massive game for us and if we can win, we will get back close to the top four which is where we want to be,' said Lucas.[LNB]'It's the perfect game for us to try something different and show that we can improve from now until the end of the season.[LNB]'If we win, it will give us a lot of confidence to go into the run of games we have over Christmas and we are all positive that we can change things around.'[LNB]Rafa Benitez will make several changes to the side that was beaten by Fiorentina on Wednesday and Fernando Torres is poised to start for the first time since November 4.[LNB]He undoubtedly will sharpen Liverpool's cutting edge, which was so clearly blunt last weekend at Ewood Park in that drab 0-0 draw.[LNB]'We had a chance against Blackburn to improve our position but we could not do that and we were very disappointed,' said Lucas.
