Defense is better but now the offense sucks - 2021 Jan Transfer Thread

Time to move on from the summer thread and talk about Jan. Arteta has done a good job shoring up the defense given the personnel we have but the offense has taken a hit. You could make equally successful arguments that the issue is scheme and personnel. The question becomes... what (if anything) is done about it in Jan? Will the roster change at all? Who stays & who goes?
