Sergio's general play is FAR superior to that of Cavani and Falcao. He is one of the most skillful and talented forwards in the world, his finishing is just not at the level of the best goal predators. Cavani and Falcao are lethal finishers, as good as Van Persie in that respect, and will work hard to find positions to receive the ball. But put them together and they'd be a very uncreative forward line who could cancel each other out. They need to be surrounded by/partnered with someone skillful to get the best out of them (Cavani has had Lavezzi, Insigne, Pandev for example, Falcao has Adrian, Costa, Turan).
