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.
"I hope I am [staying], I believe so -- but now you have left me shocked," he said. "You are pulling my leg with that about Xavi, no?"
Xavi's exit would add to a major shakeup of the Barca dressing room ahead of next season, with past mainstays including Victor Valdes and Carles Puyol also having moved on.
Luis Enrique is in place as the new coach, while goalkeeper Marc Andre Ter Stegen and midfielder Ivan Rakitic have been signed and moves are reportedly in progress for Real Sociedad keeper Claudio Bravo, Atletico Madrid midfielder Koke and Napoli centre-forward Gonzalo Higuain.
Wide attacker Pedro Rodriguez, who told ABC in quotes reported by Sport that the overhaul planned by Blaugrana president Josep Maria Bartomeu was positive, said he would be staying.
"There will be a deep change," he said. "But it will be good for the club and we are relaxed about it."
