West Ham have had an improved offer in the region of £40m for defender Max Kilman accepted by Wolves.
The Hammers had an opening £25m bid rejected by Wolves last month for their captain, which fell considerably short of the Molineux club's valuation.
But West Ham have upped their offer by around £15m and have found an agreement for Wolves over a move for the 27-year-old.
New Irons boss Julen Lopetegui is now set to be reunited with Kilman, whom he managed in his nine months in charge at Wolves.
