Rosell insists reports of agreement over a €40 million deal are wide of the mark.
"The €40 million is wrong," said Rosell. "Barca pays €29m and we are very happy, because we said we would not pay more than 30 and we succeeded.
"Then, the bonuses would mean another five million, but that will be discussed tomorrow (today) in more detail."
Rosell added: "He cost a lot. It was a soap opera for several years. Tomorrow (today) contracts will be signed and we welcome home one of our own."
