The criticism has been around for a few years now and is largely tied to the defenders and midfielders Warnock brought in with parachute payments, his spending choices have also restricted our budget to change things since, and overall playing philosophy of the club. It's the young players and more careful signings that change things around but will be take time.
Remember, i) it's pre-season and will be forgotten about after our first game and ii) everyone at the club knows about the issue are betting that the Championship is still more often Luton away than Swansea at home from last year.
