To sum up the January transfer window for Arsenal in three words, it would have to be 'improved squad depth'.
Heading into the new year, it was clear that the priority for the Gunners was to sign a defender, midfielder and forward. Come 11pm on deadline day it was mission accomplished by Mikel Arteta and sporting director Edu Gaspar with a total of £54million spent across deals for Leandro Trossard, Jakub Kiwior and Jorginho.
If there is one concern about Arsenal and their capacity to fend off competition from Manchester City and last the distance in the Premier League title race, it is whether their squad is deep enough to cope especially if a key player - like Thomas Partey for example - suffers a long-term injury.
