Basically we need to bring on starters in maybe 4 positions, and around 4-5 squad players, depth or competition as well, it's a huge amount of work and for the second group the quality depends almost on the first in a way.
Don't think many would argue we need a starting centre mid, starting right winger, starting attacking mid and starting right back.
On top of those we'd need another centre mid, another right side player, a second left back. And either another full back/centre back who can develop. Can argue a third striker should be required also.
The squad we have is already super small and that's factoring in players who simply aren't good enough - Patterson, and/or who need loans - Chermiti, Tim and Armstrong.
Right now we can't loan any of those three out or offload Patterson as they are literally first backups - which clearly they aren't ready to be at this level yet.
