We desperately needed an attacking option off the bench, a bit of speed and flair.
Let's face it, Sissoko isn't going to improve. We can only hope that N'Koudou or potentially Marcus Edwards becomes that player, because it looks like we've failed to sign anyone in that mould this window.
Isn't Son that option? He won't be a starter once we bring Sanchez into the team and play 5 at the back most games.
