The internet section of our fans aren't happy with this signing at all.
Said it before, HG, brings a tempo to the game, also has a shot on him (something we miss from midfield), PL proven, probably added somethings to his game from his time in Spain/under Simeone.
The judgement of this transfer is really if there is another to follow, get Souza, Gallagher and another (passer or attacking player) and the window looks very different from just the two of them.
Either way, he probably starts on week-end, which is always a good view of a transfer.
