I don't think there is much more to see from Vinnie. He's fine as a deputy against lesser opposition but will never have the quality to break into the first team.
Bergjwin still has room to improve but he has been shocking this season lets be honest.
Bergwijn has but when he first came you clearly see the talent, great close control, speed, power, looked like he had something about him. Now he looks scared, as do many of our players, that comes from the manager and the atmosphere. We have little in the way of attacking patterns, I have seen lower league teams look more inventive then us.
Get the manager out, being in someone like Poch who can coach attacking football, work out who is trouble or not good enough then make sales.
