I think this is the main concern for many Town fans. We dont want the all to often "one for the future" type signings we have had recently.
We need players that can challenge for a starting slot and have experience in L2/L1 or higher rather than the Premier U21/U23 leagues who have had maybe one loan spell previously.
There is a real expectation management problem this season as well. Most seasons we would reasonably expect to be top 7, as the assumption is that our support would put our budget somewhere in that range.
This season i think we all know there are at least 7-8 clubs that seem to have budgets in excess of ours. That's a hard pill to swallow for a club that really should be a league one club.
That means we need to over achieve this season to hit the clubs aims, and the fans requirements.
Everything has to go well if we are going to 'over' achieve, and that for most of us would include having the squad together as soon as possible. We can't afford to still be putting the squad together when we are 4-5 games into the season etc. Every game counts more than ever next season.
Still not even July yet. No panic yet. However i do hope the first signings are players that give the club some hope. If they are squad players or young potential then i think people are going to get very worried very quickly.
