Stoke and Fulham also keen on Scot.
Sunderland, Stoke and Fulham are locked in a three-way battle for Wolves forward Steven Fletcher, with the midlands club demanding £10 million for target man.
Wolves new boss Stale Solbakken has insisted the club will not sell the Scot on the cheap despite their relegation to the Championship, reports the Daily Mirror.
Fletcher is reportedly on the verge of handing in a transfer request at Molineaux and Solbakken has admitted he faces a struggle to hold onto the 25-year-old and strike partner Kevin Doyle.
“Fletcher and Doyle and the other strikers are experienced players we want to continue having here,” said the Norweigan.
“But everyone knows that, in football, money talks.
“They’re players of great value for us and at this moment in time they’re Wolves players. And I hope they will be at the start of the season.”
Solbakken is adamant there have been no bids for Fletcher so far but is bracing himself for an offer from Martin O’Neill’s Sunderland, who have decided against pursuing Arsenal forward Nicklas Bendtner.
“It’s one thing what we’ve been told and one thing what’s actually on the table,” Solbakken said.
“There are no offers at the moment. If there are key players who we rely on here that, for one reason or another leave the club, we must have very good players coming in to fill their roles.
“This doesn’t just apply to us – this is the same is for any team. There’s always one bigger fish out there that you have to keep up with.”
