Yipe based on APL slashing the payment to all clubs by a reported $1M, I doubt they the club will fill all the import slots. That's even if Zawada & Salas both leave, and Ball is naturalised.
The priority keeping Barba, Kraev & Pennington, plus upgrading contracts of the younger players so they feel they are rewarded after their break out seasons. Welnix might review the situation in a few months, with some clear air, depending on which players are sold in the next few months, and if there is any extra cash in the kitty. Like they bought in Salas late.
There is no rush, most of the squad are contracted. I wouldn't expect news on any new player signings (if any) for awhile, aside from hopefully Barba & Kraev being re-signed. So a bit pointless suggesting formations, possible signings etc until is some clear air. But hey it's the off season.
