But the playmaker insists that is not his priority and his sole focus is on success with Japan at Brazil 2014.
"I think everyone knows I want to do well at the World Cup, and I'm sure everyone else does, too," the 25-year-old said at Japan's training camp.
"But I don't want to get my priorities mixed up here – the important thing is for Japan to win at the World Cup.
"I'm not using the World Cup as a place to showcase myself for [van Gaal]. I'll deal with that after this tournament is over."
