The Republic of Ireland international played a starring role in a shock 5-2 Premier League triumph for Sam Allardyce’s relegation battlers at Stamford Bridge, coming off the bench to net two excellent goals.
Such a display continued Robinson’s brilliant record against Chelsea, with all five of his career top-flight goals having come in meetings with the Blues.
However, an otherwise memorable day for the 26-year-old and West Brom was marred by racist abuse sent on social media.
“West Bromwich Albion has contacted West Midlands Police to report racist social media posts directed at Callum Robinson following Saturday’s 5-2 win over Chelsea,” West Brom confirmed on Sunday morning.
“The despicable Instagram posts were sent in reply to the Republic of Ireland international after he scored twice in a memorable team performance at Stamford Bridge.
“The club is appalled by the messages and will offer Callum the help and support he may require in response to the incident.
“Albion will continue to confront all forms of discrimination and will assist the authorities with their inquiries, seeking the toughest available legal punishment.
“It is deeply disturbing that scoring two goals in a football match can provoke a reaction of this kind.
“There is No Room For Racism. Anywhere. Challenge it, report it, change it.”
Chelsea said they were “disgusted” by the abuse of Robinson and vowed to take the strongest possible action if it was found that a season ticket holder or club member was involved.
“Chelsea FC is disgusted with posts on social media this evening targeting West Bromwich Albion player Callum Robinson,” Chelsea said in a statement.
“Chelsea FC finds all forms of discriminatory behaviour totally unacceptable.
“Racism has no place at this club and where there is sufficient evidence of a Chelsea season ticket holder or member involved in such behaviour, we will take the strongest possible action against them.”
