If Trezeguet plays football and doesn't just stand there, waiting for a decent pass wich will aloud him to score with one simple kick on the ball, Juve is 10 times more dangerous than otherwise. He's quite good technically, he has the ability to deliver a decent pass or cross, he's a much more complete striker than some people (Domenech...) believe.
Not exactly . Most of the time ,we actually need to Trez to be just standing there . He's a penalty box player , a poacher , not a technical player at all . He has some nice passing yes , but that's very ordinary for a world class player like Trez . He can't drop back like Dp as you suggested because he doesn't have the dribbling skills or control Alex or Camo have . His specialty is scoring goals , it's what he does best . He's not a crosser or a creative player .
Lots of people dislike players who just stand there infront of goal , including myself . It's a matter of taste really . I prefer players like Rooney who are more mobile and versatile in other aspects of the game besides scoring , lot's of people however , prefer the classic n.9 player who waits for the slightest of chances to score a goal .
Trez isn't gifted technically and no , he shouldn't drop back to midfield and occassionally deliver crosses like Del piero . He's not that type of player . He should stay inside the penalty area and go out only if he wants to combine with Del piero , Trez , Nedved etc... That , he could do , but asking a player like Trez to move out on the wings and deliver crosses is like asking Cannavaro to play as a SS .
