Pep Guardiola has said “racism is everywhere” following the alleged racial abuse of Manchester City forward Raheem Sterling in a game at Stamford Bridge.
A police investigation is under way into an incident involving Sterling during City’s 2-0 Premier League loss to Chelsea on Saturday.
“Racism is everywhere, it’s not just in football,” said Guardiola on Tuesday.
“We have to fight to make a better future for everyone, not just in England but everywhere.”
Chelsea say they are “fully supporting” an ongoing police investigation.
The Premier League club have suspended four people from attending matches while the investigation takes place.
A Chelsea statement said evidence of racist behaviour will result in “severe sanctions, including bans”.
“Chelsea Football Club finds all forms of discriminatory behaviour abhorrent,” the statement continued, adding that the club “will also fully support any criminal prosecutions”.
The Spaniard added: “I appreciate what Chelsea did and if it happened in my club we would do the same.”
