#3 Yannick Carrasco
While the forward line in Arsenal is a stable one with Aubameyang and his partner in crime Alexandre Lacazette, the lack of wing options means they rarely play up front with each other. If they play together, one has to operate from a wing.
The addition of a quick and tricky winger would also eliminate the need for central attacking players of Ozil, Iwobi and Mkhitaryan having to play where they are least effective. Iwobi, to be fair, has done a moderately good job with that role this season but Chinese-based Belgian international Yannick Carrasco will give the club something different.
Apparently frustrated by his time in China, a loan move away from Asia to the Premier League does not sound far fetched. The quality of the player means Arsenal will have competition to sign the player. Nicolas Pépé and Cristian Pavón are speedy wingers who have been long linked with Arsenal, but Carrasco seems much more possible in this window.
