Antony still tops it for me, but he's right there below.
I still remember people here getting exasperated with me in the transfer thread for him because I was adamant it was an idiotic move and wouldn't work. The worst was honestly all of the Chelsea fans acting like they were letting fecking Gianfranco Zola leave "oh you'll love him, he'll be an Old Trafford favorite"
Said it recently, but there's a very good chance the Antony/Mount transfers are the main reason Ten Hag is unemployed right now, because if you take that 140m or so and get Kudus and Caicedo or something instead then our results probably don't end up being bad enough to bin him off yet considering what it took to actually get rid of him.
