She wrote on Twitter: "During the match last night people in the crowd threatened my family, wished death upon my mom and dad, called me names that I can't repeat here and told my fiance's niece and nephew (who are 10 years old) to sit down and shut the f*** up.

"Meanwhile security and staff did nothing to prevent this and even accepted this to take place."
