As posted on the Current Squad thread:
This was the position before the window opened:
Total: 25
Contracted: 21
In on loan: 6
Out on loan: 2
Average age at 31 December 2020: 23 years 0 months
(excluding players out on loan)
At the end of the window:
Total: 24
Contracted: 22
In on loan: 5
Out on loan: 3
Average age at 31 December 2020: 23 years 0 months
(excluding players out on loan)
So, we have one player fewer in the working squad than we had before, but one more under contract; one fewer in on loan, and one more out on loan. And the average age remains exactly the same.
