from what i've seen of beckford, i don't think the issue is that the premiership is too much for him. He has shown that he can get into scoring positions, which is the difficult part imo. once he's beaten his man and has the ball at his feet, finishing is almost the same regardless of the league. he's creating great opportunities, and is doing well to find space in attacking areas against premier league defenders, so i think its just an issue of confidence.
i really think the goal will help, it might take a season or two for him to fully hit his stride with us (shame he made the step up so late in his career) but i definitely see a lot of potential
