I've always quite liked Bentley actually and after seeing him for England U21s I thought he could have a real future, and still can, but I feel that like Upson he will have to go to another team. With Wenger always buying other young foreigners I don't think he'll get a look in. I could see him playing somewhere like Birmingham, don't know why, but maybe because I put Bentley in the same bracket as Pennant, a promising player but not given the opportunity to shine.
While I'm at it I'll give my opinions on some of the other young players. I've been pretty unimpressed by Reyes. For the amount of money spent on him I just can't see what he's added to the side. Had a bright start to the season, but then I heard little about him.
Senderos looks like a competent enough defender, but his inexperience does cause him to make mistakes sometimes. Right now I'd say he's good enough cover for Campbell and Toure. Fabregas has a lot of potential and even though he is very young, he showed he can handle it in the Premiership although I wouldn't put him in the Vieira role yet. Van Persie I think is the pick of the bunch. I can definitely see him playing a bigger role in the team this year. He'll be a great replacement for Bergkamp. So far I've been really impressed by him.
