I'm normally very against leaving business to be done in January. But it is possible that it will be slightly different this time. The season will only be about 16 games old when the window opens, and usually it's around 22. A new signing can have much more of an impact if they sign for over half a season and lots of players failed to make moves this week too.
I really would like Josh King, but it is conceivable that we could find decent cover in January unlike most seasons. I'd just prefer we didn't need midseason signings. A lot could happen in another 12 league games before then, not to mention the cup quarter final.
