Of course he's more than just a poacher, definitely pretty complete as a striker but his technique and passing ability isn't as good as Aguero's is. I think Falcao's at his best when he's at the end of chances created, rather than linking up play constantly (which he isn't amazing at but he isn't bad at either). His strengths are his finishing ability and his off the ball runs but can come up with other moments of brilliance here and there. Sergio is more rounded as a striker. A pure 9 with a pure second striker I think. It would be an interesting combination.
