Leicester City striker Shinji Okazaki on Saturday warned Japan not to take its foot off the pedal when it faces Saudi Arabia away in its final qualifier for the 2018 World Cup finals.

With Vahid Halilhodzic's men having already secured qualification for Russia after their 2-0 home win over Asian champion Australia on Aug. 31, Tuesday's game in Jeddah is effectively a dead rubber for the Samurai Blue.

Japan has already won Group B and Saudi Arabia will be looking to grab the group's other direct qualification spot, with Australia, which plays Thailand in Melbourne on Tuesday, hoping to do the same.
