1) Jordi Alba
Pretty obvious. Jordi Alba has been providing the spark to every game he has played. Running up and down the left flank, the Spanish left-back has been amazing so far. He has acted as an extra man in all attacks created by Barcelona.
He has been floating in crosses and using his incredible pace very well to beat opponents and help to create chances for the team. Having been in the team for quite some time, Alba now gets to express and play his style of the game. He charges down the left flank, making numerous dribbles and the next second you can see him helping the defence too.
While Neymar was present at Barca, Alba didn't get to attack the way he likes to, but now there seems to be no hurdle for him. He almost has a telepathic connection with Leo Messi, as most of the passes directed inside the opposition box has met Messi, and you know what happens when Messi has the ball in front of goal.
Valverde has brought out the best of the Spaniard, after he was highly disappointing under Luis Enrique. Alba has provided 3 assists in the league, so far, which is good enough for a defender.
Moreover, he has been attacking more which enables Messi to play as an attacking midfielder from where the Argentine can score and as well as assist goals. So Neymar's absence has not been felt on the left wing and all credit goes to the Spanish full-back.
Certainly, all Barcelona players have high regard for the Brazillian and stand firm on their decision to not criticise him for his move away from the Spanish giants.
But, according to the stats, Neymar's departure has not affected the performance of the team, and has, instead, brought out the best of many players - which truly proves that no club is just about a few players.
It's about the squad and it's the team spirit that wins you trophies.
