Hibernian forward Jason Cummings will have six Championship clubs watching him in Sunday's Scottish League Cup final against Ross County, according to Friday's Daily Mail.
Cummings has scored 20 times in all competitions this season and has been linked with several English second tier sides in the past.
According to the same paper in December, Burnley, Leeds United, Sheffield Wednesday and Brighton & Hove Albion were all interested in the 20-year-old, with Nottingham Forest, Derby County and Wolverhampton Wanderers also linked by the the Mail, Sky Sports and Sun respectively.
"If it’s just Bristol City watching Jason, I’m surprised," Stubbs said. "He’s obviously doing very well. He’s still got 16 months left on his contract.
"We’ve offered him a new one and we’re still hopeful he will sign it. I am very comfortable about it. If it does come to a situation, he’s worth a lot of money."
Edinburgh-born Cummings, who's been capped four times by Scotland's Under-21 side, made his debut for the Easter Road outfit in 2013 and has scored 41 goals over the past two campaigns.
Hibs have been exiled from the SPL for the past two seasons and are currently third in the Championship with nine games remaining.
