I think Bendtner is a big game player. He's sort of lazy based on his last two years in England. He was never given the chance for real in Arsenal and his loan spells didn't match his ambitions. He could thrive here in Juve! He will need to do a lot of fitness first as he's not the kind of player that runs for every ball - and he isn't used to those duties. If given a fair chance I definitely see him as a third choice starter by January. Matri has shown good form in pre-season but I guess we've all sort of concluded that he's reached maximum capacity by now.. Bendtner on the other hand - tons of potential yet to be fulfilled.. He's not the finished product but he is a gem worth polishing IMO..
Right now I would start Matri ahead of Bendtner but that is because of his pre-season performances, his knowledge to the tactics and him being Italian (Bendtner will still need some time to learn basic phrases).
Danish national coach Morten Olsen welcomed the move to Juventus, Bendtner being the first choice striker for the national team for the past 3 years, it's about time he takes his football to the next level. In Italy he'll have to show himself from scratch - in England everyone has an opinion on him whereas in italy he's fairly unknown - and those who know of him only know of him from his reputation off the field. New manager, new fans, new media - it's a fresh beginning for him and im sure he'll do everything he can to impress us all. The man want's to be the worlds' best so his ambitions will definitely match our expectations.. Not that I think he ever will become worlds' best but he could be a top 10 striker in the world IMO. (RvP being 28 before making his final break through)
