There probably is mate. I'm not too up on spending so much on him but I like to take things in perspective.
Walsh built a team out of players we would have turned our noses down for. It turned out to be a success in the end. Koeman is building a squad rather than a team bit by bit. As williams is clearly an improvement and Gueye looking a bargain, stekelenburg being solid etc I trust whoever they want to serve the specific role they are signing them for.
So for the time being I'm stepping back from having an opinion on these new signings and just looking forward to seeing whoever we sign, whether it's witsel mata or Bolasie
