Keisuke Honda admits he could leave CSKA Moscow this summer.
The 24-year-old shot to prominence at last year's World Cup in South Africa by helping Japan reach the last 16 but admitted his career had reached a crossroads.
"It's agonising," Honda, who has been linked with English Premier League clubs Liverpool and Arsenal, told Japan's Nikkan Sports newspaper.
"I can't stay like this. I said I wanted Japan to win the World Cup. I was MVP at the Asian Cup in January but I'm still not happy with things."
