West Ham and Fulham are rumoured to be the sides interested in the winger, with the goalkeeper reportedly attracting interest from Liverpool.
The two London clubs are thought to have lodged bids of around £9 million for Jarvis, with the Anfield outfit rumoured to have made a £500,000 offer for De Vries, but chief executive Jez Moxey has confirmed Wolves will not sell unless their valuations are met.
Moxey said in a statement on the club’s official website: “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.”
Steven Fletcher has also been the subject of multiple bids from Sunderland during the course of the week – which resulted in the striker handing in a transfer request.
