Agree with this for our most recent period, Guedioura was even worse because we were expecting Bojan and Deulofeu to come in!Best Ramirez.
Worst has to be Guedioura.
Cost £3.5m, played less than 2 matches worth of minutes in a year and then had his contract ripped up in the next January window.
Gestede might have been *****, but he at least contributed.
Hard to pick good signings in Janaury but I got a lot for worst in terms of impact and just actual quality:
Maxi Haas, Chris Killen, Lee Miller, Dong Gook, Aaron Connolly, Van La Parra, Marlon King
