Huddersfield Town striker Joe Lolley has been attracting interest of two of the club's Yorkshire rivals after impressing in pre-season.
Championship sides Sheffield United and Barnsley have been linked with a move for the 24-year-old, who is believed to have caught the eye of Terriers manager David Wagner in pre-season.
Lolley endured a frustrating campaign last term in the Championship due to injury but has impressed the side in recent friendlies, and seems to have formed a good partnership with summer signing Steve Mounie.
Wagner is believed to be keen to tie Lolley down to a new contract in a bid to fend off interest from the Blades and the Tykes. Sunderland are the third club from the Championship linked with the player.
