Dani Alves said he was "in a state of shock" after being told that Barcelona teammate Xavi Hernandez is close to a move to Qatari side Al Arabi.

Al Arabi coach Dan Petrescu said the long-serving playmaker, whom Alves called "a symbol" of the way Barca play, had agreed to join the Doha club after the World Cup.

Reports in Spain also suggested the transfer had been agreed, while Xavi's agent was seen at the Camp Nou on Tuesday.

Asked for his thoughts on the matter in the mixed zone after Brazil's 0-0 World Cup Group A draw with Mexico on Tuesday, Alves said nobody's future at Barcelona was secure if Xavi could leave.

"I don't believe it -- you're pulling my leg," AS reported him as saying. "It can't be. Xavi? If Xavi leaves, who is the symbol? If he leaves, then anyone can leave.

"I do not understand it. You have left me in a state of shock. That is for sure? It can't be. Xavi cannot leave Barca."

Asked about his own future, with an offer from Paris Saint-Germain reportedly on the table, Alves said he was planning to remain at the Camp Nou.
