Brazilian star Neymar who had been rumoured to only leave his club Santos after the World Cup in Brazil in 2014, has instead signed for Spanish champions FC Barcelona on Monday, and joins Argentine World Player of the Year Lionel Messi at the red-and-blue.

Neymar signed a five-year contract with club president Sandro Rosell after choosing Barcelona over Real Madrid and the 21-year-old jogged onto the Camp Nou field for the first time in his new Barcelona jersey with "Neymar Jr" on the back.

"I am very happy, very moved to be a Barcelona player and fulfill my dream," Neymar told the crowd of 56,500 that welcomed him.

"I have come to add my part so that Lionel Messi continues to be the best player in the world."
