Manly’s Dylan Walker admits his playmaking spot at the NRL club is under threat due to the resurgence Apisai Koroisau.

After being asked to fill in for injured halfback Daly Cherry-Evans, utility player Koroisau has earned two man-of-the-match awards and outshone five-eighth Walker in their three games together.

With Cherry-Evans due back against North Queensland in a fortnight, coach Trent Barrett has a difficult decision to make and Walker fears he’s on the chopping block.
