Urawa Reds midfielder Yosuke Kashiwagi saw plenty of room for improvement following Japan’s 7-2 win over Bulgaria on Friday night in the semi-final of the Kirin Cup 2016.

Goal rushes in both halves were offset by defensive errors in Bulgaria’s two consolation strikes, which came with veteran goalkeeper Eiji Kawashima between the posts.

“I’m not satisfied with the result,” Kashiwagi said after the match. “The defence didn't click after we changed several players in the second half, and I feel like I wasn’t able to show my qualities before the match ended.

“The first half was very good and we used the sides and centre of the pitch effectively, but we have to be stronger on defence. We lost bad balls in the second half and there were times when we didn’t see their counters. We have to reflect on a lot and try to improve.”

The Samurai Blue will play Bosnia & Herzegovina in the cup final on Tuesday night at Osaka’s Suita Stadium.
