West Brom midfielder Romaine Sawyers, and Manchester United duo Axel Tuanzebe and Anthony Martial were also the victims of online racial abuse this week.
Chelsea said social media must create an environment where hateful and discriminatory actions are not tolerated.
"We add our voice to those urging social media platforms and regulatory authorities to take stronger, more effective and more urgent action against this despicable behaviour," Chelsea said.
"Something needs to change and it needs to change now."
