However Jeffren, who recently extended his Barca stay until 2012, was given a chance by Pep Guardiola in the World Club Championship and now believes he can make the grade at the Nou Camp.
"I rejected a lot of interesting offers and a lot of money to extend my stay at Barca," Jeffren told the Daily Record.
"In January I had the chance to go to Scotland on loan at Celtic but at the last minute I decided against it.
"My role at Abu Dhabi was decisive for my future. I want to play at the best club in the world with the best players.
"Playing at Barca fulfils my dreams and I have to take this chance. Guardiola has confidence in me. That was important in avoiding an exit from Camp Nou."
