West Ham are set to continue their spending spree under the guidance of Manuel Pellegrini, with further defensive additions targeted.
The Hammers have already bolstered their back-line with the additions of Fabian Balbuena, Issa Diop, Ryan Fredericks and goalkeeper Lukasz Fabianski but are now reportedly keen on signing a left-sided defender.
Italian outlet TuttoMercatoWeb states Genoa have rejected an offer of around €12m from the Hammers for the services of Uruguay international Diego Laxalt, as they seek €18m for the versatile ace.
Capable of playing at full-back or further forward, Laxalt caught the eye with his performances for La Celeste at the World Cup as they advanced to the quarter-finals in Russia.
West Ham are not alone with their interest in the 25-year-old, with Premier League rivals Everton also said to be eyeing a move, but the Hammers have attempted to steal a march on the Toffees.
However, West Ham will have to raise their offer if a deal is to be concluded.
