Koeman was infatuated with Sigurdsson from the moment he got here, we were being heavily linked with him in his first window. He loved his assist stats but had absolutely no clue how he was going to use him or what his attributes even were. The fact we chased him for 6 weeks while ignoring far more important areas of the squad, before spunking close to FIFTY MILLION POUNDS on him was up there with the worst pieces of business we've ever done.
Sigurdsson - an average player who has been alright over the course of the season. Compared to some of the other absolute garbage in our team he looks like he's been better but our former manager spent £45m on him, an eye-watering amount that should in all honesty, get you a top player and game changer.
I think lumping Koeman in with some of the other managers we've had in that time period is a bit unfair. He was much more destructive than any of them.
