West Ham are stepping up their interest in Reims striker Boulaye Dia.
Le 10 Sport says the Hammers are eyeing Dia as a replacement for Sebastien Haller.
Haller is set to sign for Ajax today, with the Frenchman having already agreed personal terms in the last 24 hours.
Dia has been on the shopping list of several English clubs this season.
Along with the Irons, Arsenal and Southampton have also been linked with Dia.
