Actually, when I think about it again, maybe Lucas can be part of a title-winning Liverpool side. I mean, United has Fletcher, and there is no question to my mind that Lucas is the better CM (though Fletcher excels at the physical side of the game). Fletcher doesn't create much from what I have seen, but he doesn't need to. Fletcher tidies up and keeps possession, and United turns to other more creative avenues (mostly Nani and Rooney) for assists.
Unfortunately, that's what we are lacking these days. Maxi has shown a lot of promise, but he hasn't often clicked with Torres, and Kuyt, while an incredible workhorse is not exactly the most creative. Perhaps what we need are better wingers and a more creative CM to partner Lucas.
