The big question now is, where will Coutinho play? Will Barca groom him for the Andres Iniesta role, or will he be used in attack?
Barca legend Michael Laudrup believes the Brazilian has been brought in to help the club better prepare for life after Messi.
“In recent years, Barcelona have lost some important players: Xavi Hernandez, Neymar and others, like [Carles] Puyol,” he said.
“So they need to build on this, even if they are top now, because there will be one day when Messi is not there.
“The only way you can do that, knowing you cannot find a new Messi, is to try to get three, four, five very good players to fill the gap that he will leave.”
