The January transfer window has a little over a week before it closes across Europe's top leagues for the season, and things are beginning to pick up steam after a rather methodical first few weeks.
One of the early signings of the window has already had a major impact, with Erling Haaland netting a hat trick off the bench for Borussia Dortmund in his sensational debut over the weekend following his arrival from RB Salzburg.
Other teams are in search of difference-makers just like that and have just days remaining to find them or risk going to battle with what they've got for the pivotal matches ahead.
