West Ham are determined not to lose Michail Antonio this month.
Chelsea have added the Hammers star to their January wish-list.
The 26-year-old has been one of the Premier League's most impressive players this season attracting the eye of West Ham's London rivals.
But the Daily Star says West Ham will not entertain any offers for their star.
Antonio is a major part of Slaven Bilic's plans for the rest of the season and the Hammers boss will not part with him as the club's Premier League survival is not yet secure.
Antonio, who joined West Ham from Nottingham Forest for £7m in September 2015, has netted eight goals in the top flight so far this season.
