#4 Lack of Form
Even though he scored against Lyon in the Champions League on Wednesday night, the Brazilian has been going through a rough patch of late. Coutinho is averaging just 0.9 key passes and 1.5 dribbles per game in La Liga this season. He has just 5 assists from 40 games in all competitions so far. His form in the league is especially poor, as he has just 4 goals and 2 assists from 25 games. Going for a player who has been so poor this season makes no sense, and Manchester United would be wise to steer clear of this deal.
The Brazilian is proven in the Premier League and does have an advantage in this regard. However, Coutinho's lack of form and inability to assert his influence in a Barcelona side that lacks a player of his calibre is alarming, to say the least. As such, there is a degree of risk associated with this transfer that United do not need at the moment.
