For Celtic, the number that stands out is six in two days. That kind of late surge can cut both ways.
A late-window rush usually means a manager believes the squad needed specific fixes rather than cosmetic depth. The challenge now is less about headline arrivals and more about speed of integration. Training-ground detail matters quickly when so many pieces land at once.
At Rangers, 14 new recruits is a clear statement. Deadline-day additions often tell you a club still saw gaps that had to be addressed before the market shut.
That gives a manager more choice, but it also raises the bar for cohesion. New squads rarely click through volume alone. Roles, balance and reliability still decide whether a busy summer becomes a successful one.
Other reports also say there will be no away supporters at Old Firm Premiership and League Cup matches this season. That puts even more focus on what happens on the pitch, because squad quality and depth will dominate the conversation.
For now, attention turns to Saturday, when Celtic face St Mirren. It is the first immediate test of whether late business brings instant momentum or whether patience will be needed while a heavily refreshed group comes together.
