Lamie has been our best centre half all season, he is far better than just a squad player.
The turnaround in his form has been quite incredible, and perhaps having an international defender as his manager has had something to do with it.
I don't even know why PCAs exist.
If you want someone in January, pay for them and take them in January.
If you want them when their contract expires. sign them after their contract expires
The rest is just unnecessary complication.
