#4 Philippe Coutinho
Having shelled out more than £140 million for the player, Barca finally appear to be getting the player they thought they had signed.
The Brazilian has steadily adapted to Spanish football but still has a lot to prove at the club. A major reason behind the team's over-reliance on Messi is his inconsistency.
The former Liverpool man is definitely a world-class player who can tear defences apart on his day with some effort. The onus is now on him to step-up and complete the job he was bought for.
His versatility to play anywhere in the midfield can be used to the team's merit and rotate the key players more often.
If he manages to repeat even 70 percent of his performances from his time in England, he would be a supreme asset at the Camp Nou.
