1) Iniesta’s rightful heir
Lionel Messi might be the star of the show but Andres Iniesta's importance to the team can never be underestimated. The Spaniard is the primary string puller for the squad and Barcelona tend to suffer sometimes when he is not playing.
There are not many like the graceful Spaniard in the world and Messi most of all people have benefitted from his intelligence. His passing movement skill and balance on the ball is unparalleled and Barcelona will miss him when the time comes.
That might not be too far away considering he is already 32 with his age starting to show in his legs as well as his fitness. Once Iniesta decides to call it quits it would leave a massive hole in the team.
But Coutinho is Iniesta’s rightful heir and bears several similarities in the style of play. Granted the two are not like for like but he will essentially give Barcelona the creative spark that Iniesta has become so famous for.
It would be the perfect change of guard to see Coutinho take over the mantle from the Spaniard. Iniesta is no doubt irreplaceable but Coutinho is probably the closest anyone will come to matching his ability
