Huddersfield are confident of completing a deal for the 26-year-old, ahead of competition from Premier League rivals Brighton. Mooy's capture will smash their previous transfer record of £1.8million for defender Christopher Schindler, as chairman Dean Hoyle moves to strengthen Wagner's squad.

The deal will also represent smart business for City, who only signed him from Melbourne City last June, with Mooy failing to make a single appearance for the club.

Mooy, voted Huddersfield's player of the season, said: "Right from the start they backed me and believed in me.

"When you start at a new club that's what you want from the fans and sometimes it's what you need.

"I loved playing in front of them all season long. Always big crowds and a great atmosphere, it was terrific.
