Gabriel Martinelli is primed to be the biggest winner of Arsenal's January transfer window.
Of the six first-team players to depart the Emirates Stadium last month, there's no doubt the biggest one was former captain Pierre-Emerick Aubameyang who agreed to a mutual termination of his contract.
The 32-year-old has since joined Barcelona on a free, leaving behind a major problem for Mikel Arteta to solve in north London.
