The Ricketts family, which is aiming to buy Chelsea, says it will meet fans to allay concerns about its potential ownership.
They are one of six groups who have made their bids for Chelsea public.
The bidders are all waiting to hear if they have made a shortlist.
Fans have criticised the Ricketts family's ownership of the Chicago Cubs baseball franchise, as well as anti-Muslim comments made by the family's patriarch Joe Ricketts in 2019.
Paul Canoville, Chelsea's first black footballer, said on social media: "So I've seen and heard enough. I'm backing Chelsea Supporters' Trust and saying a big fat anti-racism NO to the Ricketts bid.
