#2 Philippe Coutinho
Philippe Coutinho is a versatile player who can play as a left winger or even an attacking midfielder. Barcelona tried to sign this Liverpool man as Neymar's replacement after he left for Paris. However, Coutinho can be the perfect successor of Iniesta and not Neymar at the Camp Nou.
Jurgen Kloop used Coutinho as an attacking midfielder in the last season of the Premier League. He adapted to his new role in a brilliant way and played beautiful football down the middle, providing forward passes to the strikers, making darting runs with the ball as well as off it.
He was a constant threat for the opposition defence as he possesses all the ability to be a attacking midfielder of the highest order. You name the attribute and he has got it - crisp ground passes, incisive through balls, runs and dribbles down the middle and accurate long shots, he has everything.
Coutinho is in brilliant form this season in the Premier League and the UCL. He has already scored 9 goals and provided 6 assists in 12 appearances. Andres Iniesta is close to the end of his prime and its high time Barcelona signs someone who can fill the void of Iniesta for years to come.
