Spain's World Cup winning hero in 2010 Andres Iniesta believes next year's tournament in Russia is likely to be his swansong at international level.
Barcelona midfielder Iniesta, 33, signed a first ever "contract for life" with the Catalan giants last week.
However, after a few injury-plagued seasons, he is hoping just to be fit in 2018 to top off a stunning international career.
As well as scoring the winning goal in the 2010 final, Iniesta helped Spain win back-to-back European championships in 2008 and 2012.
"I am realistic. There is a great chance this World Cup will be my last event with the national team," Iniesta told Barcelona-based daily Sport on Friday.
