Sky Sports sources understand Wolves are battling to hang on to winger Matt Jarvis after rejecting a £9million bid from West Ham.
The club confirmed earlier in the week that Steven Fletcher has handed in a transfer request following a number of rejected bids from Sunderland.
And now Jarvis' future is also in doubt as clubs continue to look to raid the talent at Molineux following Wolves' relegation from the Premier League.
The Hammers are understood to have offered £6m now for the 26-year-old England international with a further £3m in non-guaranteed add-ons.
But the West Midlands club appear determined to hang on to their best players with chief executive Jez Moxey reiterating that they are under no financial pressure to sell.
In a statement, Moxey said: "As we have previously stated, no player will leave Wolves unless the club's valuation is met and it is in our best interests from a football perspective.
"We wish to retain our best players, we are not under any financial pressure to sell. Players will remain here unless we receive satisfactory offers.
"These are challenging situations for all parties, but we will continue to conduct our business in a respectful manner and will honour all of our commitments.
"We hope, and expect, other parties to do likewise."
With three years remaining on Jarvis' contract and Wolves needing to pay his former club Gillingham 15% of any transfer fee, the club are keen to negotiate the best possible price.
