Wilson joined in October 2019, so the deals made since then are the ones we can evaluate him on.
Ianis Hagi - success
Florian Kamberi - failure, but a very small outlay
Bassey - Massive success
McLaughlin - success
Defoe - success
Balogun - success
Roofe - success
Itten - failure, with a fairly sizable outlay
Zungu - failure, with a very small outlay
Simpson - failure, again very small outlay
Ofoborh - TBD
Wright - success (cost very little and is a great rotational player, particularly under GVB)
Sakala - success (he's in double figures for goals despite being a rotational player, and he cost almost nothing)
Lundstram - massive success
Bacuna - failure, but minimal outlay and moved on very quickly
Sands, Diallo, Ramsay, Zukowski - TBD, these players only just got here. If Ramsay and Diallo return without contributing in Seville then they're failures, but the fat lady hasn't sung yet. It's completely mental to be writing off Zukowski or Sands after three months.
