Huddersfield midfielder Lewis O'Brien is wanted by Leeds United manager Jesse Marsch.
The Sun says the Terriers plan to offer him a second new contract in a year if they get to the Premier League.
Academy product O'Brien, 23, was on Leeds' radar last summer.
However, they failed to come up with a decent offer despite lengthy inquiries.
Instead he stayed with Huddersfield and was rewarded with a rise.
Leeds should now have the cash to meet his £10million fee but they could miss out again if their neighbours return to the top flight.
Huddersfield face Nottingham Forest at Wembley on Sunday in the Championship play-off final.
