Huddersfield are closing in on a $17 million club-record deal to sign Socceroo midfielder Aaron Mooy from Manchester City.
The Australian spent last season on loan at the club and was the Terriers' player of the year as they won promotion to the English Premier League.
Press Association Sport understands Huddersfield are in the advanced stages of a deal to pay $13 million for the 26-year-old with a further $3.4 million in add-ons.
It would smash their previous transfer record set 12 months ago when they paid 1860 Munich $3 million for defender Christopher Schindler.
Mooy made 51 appearances for Huddersfield last season, scoring four goals, and was also successful from the spot in the two playoff penalty shoot-outs which helped Town secure a berth in the top flight.
He has not, however, made an appearance for City since moving from sister club Melbourne City, joining David Wagner's side on loan shortly after arriving.
