#3: Manchester United

Manchester United have resurfaced as one of the strongest sides this season, thanks to the arrivals of Nemanja Matic and Romelu Lukaku in the summer. However, Henrikh Mkhitaryan and Juan Mata haven't exactly been in top form this season.
The former of the two started brilliantly but has disappeared as the season has progressed. In a 4-2-3-1 formation that United have mostly used this season, the left flank has been taken care of by Anthony Martial and Marcus Rashford, who have intertwined brilliantly with each other.
However, the right flank lacks an in-form midfielder and Alexis could do well by taking up that job. The Chilean can demand the wages he desires and the number 7 shirt will elevate his popularity to a greater level in world football.
However, it remains to be seen if Arsenal agree on losing another star to United after Robin Van Persie. But Alexis will have a crucial part to play at Old Trafford should he join the Red Devils in January.
