The thought of playing alongside Lionel Messi has Neymar feeling like "one of the luckiest men in the world" after the Brazilian completed his £48.6million move to Barcelona.A Brazil international since 2010, Neymar has already scored 20 goals for the Selecao and was representing his country in a 2-2 friendly draw against England at the Maracana Stadium only hours before flying to Europe. And he revealed that his national team-mate Dani Alves, a wing-back for the Spanish champions, played a role in convincing him to sign. "Alves was one of the people who encouraged me to come and he's always said good things about the place," he added. "I'll try to improve my Catalan, I speak better Catalan than Castilian. I will try to adapt quickly so that I can relax and just play football." The deal that brought Neymar to Spain includes an agreement to play two friendlies against Santos, one of which will be played at the Nou Camp. It was also revealed that the player's contract has a buy-out clause set at 190m euros (£162m).
