Neymar has targeted May 17 for a return to training and vowed to work harder than ever to be ready for this year's World Cup in Russia. The Paris Saint-Germain player, who became the world's most expensive footballer when he joined the club from Barcelona in August, had an operation on his foot after being injured in a French league game against Olympique de Marseille on Feb. 25. He has been receiving treatment in Brazil and said he expects to be training exactly a month before the five-times champions play their World Cup opener against Switzerland on June 17.
