I don't think there is a whole lot that can be done due to the nature of the position. The supply far outweighs the demand. Unlike other positions, there is only one job a keeper does. It's not like other positions in which a player might be able to play both central and out wide or play as a midfielder or a defender.
With the introduction of the NST, the next generation should (in theory) be slightly better. Next year we will have an additional 10-12 starting keepers playing regular football at the professional level. Then you have the 20-24 additional second and third keepers training/travelling at that same level. This should result in keepers reaching a higher skill/experience level at a slightly earlier age. 

Vuko bad habits, you mean coming back being lazy more like it haha just needed inspiration again...
I admire Vuks heaps, infact rate him one of our best pity he's maturing but can play here for another 2seasons at least imo.
Was brilliant at Genk, CCM reaping the rewards of fine determined experienced leader.

Danny of course did play in Europe for years. On his return he was not at the level you would expect but then Monty's GK coach (can't remember his name) fixed some bad habits he had gotten into. Now he is showing the way once again with 20 clean sheets across the ALM and AFC Cup campaigns this season. 

I don't think it's gone unnoticed that our goalies are performing very strong in the a league. We saw last night with izzo and vukovic.

At the moment we only have Ryan starting at a decent club so how can we get more keepers taking it to the next level?
