Former Celtic midfielder Shunsuke Nakamura is a major doubt for Japan's friendly with England in Austria on Sunday.

The 31-year-old, who now plays for Japanese side Yokohama F Marinos, was replaced midway through the second half of the 2-0 home defeat to South Korea on Monday and was struggling with a sore ankle during training on Friday.

"Shunsuke needs a bit more time to get back to his best condition and I am not sure if he can play," coach Takeshi Okada said, according to Kyodo News.
