Right, I think there are two different questions here.
Is Nelson good enough to play for a League Two club next season? I think yes. Despite all of the criticism on here, you've got to remember he has improved a lot over the past few seasons. Hes always been a good shot-stopper but has lacked consistency and he cant kick for sh!t. These are skills that should be learnt on the training ground, so I think the finger of blame should be pointed at Stannard and the coaching team. Nelson is still a relatively young keeper and I think a solid season next season would help him develop into a much better keeper.
The second question is who is better, Nelson or Abbey? For me it has to be Abbey. As someone said earlier in the thread when Abbey came in it was amazing to see the difference an experienced pro makes. In that first game against Chesterfield he was shouting at the defence, claiming crosses from corners, commanding the area, even pulled off a couple of good saves if memory serves.
I think in an ideal world we would want to keep them both on. I think Nelson has struggled in his development over the last few seasons as he was thrown in as the no.1 a bit too early. However we all know that we cant afford this option.
Realistically we need to keep hold of Abbey as an experienced pro and let Masters learn from him. We've seen flashes of ability from Masters but he lacks the finer points such as how to set up for free kicks from the edge of the box.
In summary, Nelson OUT.
