Betway have apologised to West Ham defender Michail Antonio after the betting firm criticised the right-back on Twitter on Monday night, according to a report.

Sky Sports claim that Betway made a hurried apology on Tuesday morning after the company posted a negative social media post about the player even though they are are the club’s official shirt sponsors.

Antonio gave away a penalty as the east London outfit opened their 2016-17 Premier League campaign with a 2-1 defeat to Chelsea at Stamford Bridge on Monday evening.

Eden Hazard converted the spot-kick before a James Collins equaliser was followed by an 89th minute winner from Diego Costa.

“Antonio has been an accident waiting to happen in defence,” Betway tweeted. “West Ham fans will hope that’s the end of the experiment.”

Betway have told Sky Sports News HQ they have “a team of passionate writers who provide impartial opinion across all sports, but acknowledge this particular tweet was inappropriate in light of the company’s relationship with West Ham”.

The report says that West Ham and Betway held a conference call on Tuesday to discuss the now-deleted social media post.

Antonio has found himself used as both a right-winger and a right-back in his time under Bilic and while the 26-year-old has been widely praised for his attacking threat, his defensive ability has left much to be desired.

In other West Ham team news, fans have expressed their disappointment at new signing Havard Nordtveit following his debut performance in the team’s 2-1 loss to Chelsea.
