Crystal Palace have opened discussions with West Ham United over a January move for striker Diafra Sakho, according to a report.
The 28-year-old, keen to quit the London Stadium this month, is said to have arrived at the Eagles' training base on Wednesday morning to undergo a medical.
Before an announcement can be made, though, Sky Sports News reports that Palace still have to come to an agreement with Premier League rivals United regarding the Senegal international's valuation.
Sakho announced in October that he would seek a West Ham exit in the New Year after seeing a deadline-day switch to French club Rennes fall flat.
Everton, Newcastle United and Swansea City have since been linked with the former Metz ace, who is said to have fallen out with boss David Moyes soon after the Scotsman arrived in West London.
