South Africa captain and Everton midfielder Steven Pienaar has quit international football because his \"body is tired\", the national football association has announced. Pienaar, who succeeded Aaron Mokoena as skipper after the 2010 FIFA World Cup™, revealed his decision in a letter to the association, which was read out ahead of a national squad announcement. The slightly-built 31-year-old midfielder, the only South African footballer featuring regularly in a major European league, said he could no longer cope with the physical demands of playing for both his club and country.
