I've literally just showed you the table.
We have room for 1 more and another 2 if Cancelo and Laporte leave.
I'm going to be respectful here, and trust you mean well and have just got your counting wrong, which can happen.
The 17 spaces are currently full. It says 16/17 at the bottom, but if you count them, there are 17 names there. Which is missing Steffen btw, whose loan has ended and is our player till he finds another move, but lets ignore that.
If you take away Laporte and Cancelo, that leaves 15 out of 17. Not 13. The two names in blue, although home grown, take up those spaces as we are 2 over the 4 elsewhere. and we do have the 4. And another 2.
Our squad is currently 22 senior players, plus Foden and Palmer.
I'm sorry, that's not a small squad.
Don't even start with the players can be left out of the CL squad because you don't consider them good enough shit. Even if true, which it is not, if we have to leave players out of the CL squad, then our squad is too big, not too small.
