With two right sided options likely to be available therefore Sky sources claim the Hammers are ready to let Antonio move on but want offers in advance of £15 million for a player who cost them £7 million from Nottingham Forest three years ago.
However, boss Manuel Pellegrini will have the final say and is reported to have been impressed with Antonio during his fitness work as he returned to the squad in Switzerland today (Mon).
While no offers are understood to have yet been made for Kouyate, the asking price for the 28-year-old is thought to be around £10m.
All the decisions will be in the hands of Pellegrini as he acts out his words of yesterday when claiming the Hammers would be building a very strong squad for the season.
