Like I said on numerous occasions bar one and half games we've played hoofball. The introduction of a player who koeman didn't want has madev us press a bit.
We lacked the cutting edge because the majority of the season we have been toothless going forward, it's been pretty abysmal actually because of how we are approaching games. It's right there in black and white. Opposition goalkeeper's are rarely tested against us
And that needs to improve.
As you said, January is massive, because these players haven't been scoring enough goals since the start of 2016, really.
They were so effected by the bad defending, that they lost the thing they were so good at in the first place under RM. And nothing I have seen suggests that any of them will get it back.
