The 20-year-old initially joined the Blaugrana in January from Atletico Mineiro in a €12.7m deal in a convoluted operation in which both Barcelona and Real Betis paid for half that sum each.
Both clubs now co-own the right-back but he has exclusively played for Betis since his arrival, with Barça’s option to sign him permanently.
“I started my career at just 16 then three years later I am at Betis, but I am owned by Barcelona and in the Brazilian national squad,” Emerson claimed, in quotes recently carried by Diario Sport.
“My career has only just begun but my aims are to win the Champions League and the World Cup.My adaptation to Spain has been excellent, not only on the football pitch but also with the food, the people and the languag. My dream is to succeed as a Barcelona player, to make history and start by winning titles.”
