West Ham's sponsor Betway has released a statement saying its tweets on Michail Antonio's performance versus Chelsea were "inappropriate".
Online bookmaker Betway has issued an apology after it tweeted criticism of West Ham player Michail Antonio – despite being the official shirt sponsor of the Premier League club.
Playing at right-back as opposed to his customary position on the wing, Antonio endured a torrid outing in West Ham's 2-1 defeat at Chelsea on Monday as he gave away the penalty for the hosts' early second-half opener at Stamford Bridge.
He was replaced by Sam Byram shortly afterwards, at which point Betway posted a scathing assessment of his performance on its official Twitter account.
