Fifa disciplinary chairman Claudio Sulser said yesterday that Russia will be punished if their supporters show any form of racist behaviour at the 2018 World Cup in the country.

Sulser’s comments come just a fortnight after CSKA Moscow were forced to play their home match against Manchester City in the Champions League behind closed doors following past violent and racist behaviour from their supporters, although 350 Russian supporters were able to gain entry to the ground on the evening.

“You have to change it to not only discriminatory but appropriate in this case.

“The Commission analysed it and said it was not discriminatory. Some say the word is discriminatory, some not.

“This is the problem because it is not like mathematics wh
