l would suggest tall developing key defender would be priority ahead of some of those.3 spots id be looking at,
Pacey Medium defender - id say an upgrade on Cincotta, not saying hes done anything wrong but i feel he could be upgraded on in most aspects.
A Midfielder with pace to burn, i feel we are a slightly one paced midfield. We dont have any line breakers at all.
Another medium fwd. Jack martin with a new set of calves.
Voss likes big bodied strong midfielders, in 2 years time Hollands will be another quick midfielder once he builds his body.
