West Ham United are prepared to offer £25m to Premier League rivals Swansea City for central defender Alfie Mawson, according to a report.
The 23-year-old emerged as a potential target for the Hammers earlier this month following some bright individual displays in a season to forget for his side.
In a bid to fend off interest from other interested clubs, the Daily Mail claims that West Ham are ready to move quickly to ensure that a deal can be finalised early in the January window.
Swansea are said to be willing to do business if Mawson's value is met, with 15% of any fee expected to go to former club Barnsley.
The same report suggests that £20m will be handed over upfront in January, while the other £5m will be paid in instalments if various add-ons are triggered.
