Transfer speculation continues to mount as Yang Hyun-jun has been linked in recent days with a move to Preston. The forward, currently playing for Celtic, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. Norwich and Birmingham remain in the background, but for now, Preston are leading the way in ongoing talks. Preston's current 1.38 goals scored per game is close to average. Yang Hyun-jun would be seen as someone to make them more dangerous and clinical in the box. No fresh speculation surrounds Celtic or Preston regarding other transfer targets.
