Team composition ... only 3 players???!!

[Raykco]

Here's something I saw today:

Starting XI: 5 players
Subs: 3 players
Reserves: 21 players

This sort of thing seems to be only possible on the PC version. The mobile version does not allow you to hide players on your reserve roster if their are openings in the Starting XI or 7 Subs.

My other question is, how can you carry 29 players? Are 7 of these players acquired, but not yet signed? If so, how long can you carry unsigned players? I've done this with a couple of players at a time where I held them for several hours before finally sacking or selling someone on my roster to make space. Recently I managed to hold onto an unsigned U21 player for 3 days until I had enough tokens to sign him.

How long can you carry unsigned players?

Any thoughts?

Unsigned players can be kept for 7 days. After that, they leave as free agents.
