Technical area.
As for not spending money, what's the obsession with how much we've spent compared to others? Surely it's the quality that we should be worried about?
As an example, we've bought in Cleverly, Henen, Holgate and Deulofeu for what £5m? 2 of those for the first team, both of which have premiership experience and have improved the squad, and 2 for the future with minimal outlay. Plenty of clubs have spent £8-10m on one player who's unproven at this level, see Villa, West Brom, Stoke, West Ham and plenty more.
I'm not stupid and I appreciate we have tighter financial restrictions than most, but to solely judge how a transfer window has gone by comparing the amount spent by others is pointless.
If we only spend £5m this window and bring in no other players then obviously I'm gonna be back here going absolutely mental in a couple of weeks.
