Worst January signing ever?

Kalvin Phillips must be in with a shout.
From his assist for Solanke within 180 seconds of his debut, to a red card against Forest. Today he came on at 3-1 up and almost immediately conceded a penalty that swung the game dramatically (tbf it looked pretty harsh).
Following that Bournemouth game, West Ham lost 3-0, 6-0 and 2-0 and they have only won twice in Phillips Claret and Blue career - a 5-0 in Europe where he played 4 minutes and a 3-1 over Everton. He was also hooked at half time with West Ham 2-0 down at home to Burnley - a game West Ham recovered in to draw 2-2.

With Edson, JWP, Soucek, Kudus, Paqueta and Bowen, midfield was a strength of West Ham so why they felt the need to bring in Phillips I do not know. Having been pretty inactive for 3 years it was always likely for him to be very rusty.

At least for English fans it is surely impossible for Southgate to take him to Germany...
