Jeffrenas should sign a contract with Lisbon's "Sporting" club in the near future.
According to unofficial information, the Portuguese team has agreed to pay slightly less than 5 million euros for the footballer, but "Barcelona" will have the option to buy him back within two years.
"Jeffren has helped us a lot in the last three seasons, but considering his age, it would be better if he could play more," said Barcelona coach Pep Guardiola.
Last season, Jeffren played only eight matches in the Spanish championship and scored one goal.
