I think the problem we arguably have is that those who seem ready are quite forward playing - I'm 90% sure I'm right in saying Bostock & Rose are both AMs, then we have the likes of Obika & Pekhart who are strikers, all of whom I'd like to see a bit more but I don't see an easy opening for them. As I remember Pekhart is a big frontman who was supposed to be learning from Berbatov with a view to breaking through some time soon, he's been around for a good few years so surely now's the time for him to at least get a squad number.
if, as seems inevitable, Bent's off this summer perhaps the plan is to have 3 'main' strikers and bring one or two of them through? We'll have significantly less games next season and it's not been possible to keep 4 first team strikers happy up until now, but I've consistently heard good things about Obika so perhaps it's time for him to step up a bit. A striker like him or Pekhart is unlikely to be used a lot so shouldn't be a risk as such, but can learn a lot from the bench.
