I'm not saying he's "just" a goalscorer because he definitely is more (Lewa and Falcao would be just goalscorers). Whenever he gets the ball he can create or score (rather spectacularly) but he isn't the one who brings your attacking play to life the way Suarez does. Any forward line is driven by dynamic players (someone who is mobile, carries the ball forward, etc.) and makes that transition from buildup->final third. Ribery and Robben do that for Bayern, Messi and Neymar for Barca, and Suarez for Liverpool. The thing with Suarez (and Messi) is that he plays that role as well as scoring. Ibra isn't mobile enough to bring the play forward like that, but whenever he has the ball he can do and often does something amazing with it. Ibrahimovic is like a target on steroids with a huge variety of abilities, Suarez is a dynamic attacker on steroids.
