You may prefer him as the lone striker, I don't. He is more useful overall but with Camo, Diego, Giovinco behind, I'd take a poacher ahead of him any time. If Trez played the full match against Sampdoria I'm certain he'd score just as much, perhaps more than Amauri. The team was simply clicking that night and were unstoppable. Against Napoli we lacked Sissoko and we lacked Camoranesi for practically the whole match, which makes a world of difference to our team play.
I appreiate Amauri, I do and I don't bash him at all, but when it comes to Trez vs Amauri, I feel the former is much underrated and the latter overrated.
