Gamba Osaka manager Kenta Hasegawa will not renew his contract at the end of the 2017 season, the club has announced.

Hasegawa took over the side in 2013, leading Gamba to that year’s J2 League title. In their return to the J1 League the following year they won an unprecedented treble, taking home the title, J.League Cup and Emperor’s Cup.

However, results have not entirely lived up to expectations since, with the club now taking steps to select a successor.

“As a club we are thinking about how to advance to the next stage, and after careful consideration we have agreed that now is the time for Mr. Hasegawa to move on,” club chairman Takashi Yamauchi said.

“We are as always grateful that he stepped in to save the team during our time in the J2 and guided the club to four trophies.”

At the conclusion of the MEIJI YASUDA J1 League’s 24th round, Gamba were in seventh place with 39 points, 13 off the pace of leaders Kashima Antlers.

They also advanced to the semi-finals of the J.League YBC Levain Cup, where they will face city rivals Cerezo Osaka, and the fourth round of the Emperor’s Cup, where they will play Kashiwa Reysol.
