Promoter Eddie Hearn has revealed that Manchester United striker Zlatan Ibrahimovic is scheduled to make an appearance at London's O2 Arena for the world middleweight title clash between Gennady Golovkin and Kell Brook.

The showdown between arguably the sport's best pound-for-pound fighter and IBF welterweight champion Brook sold out in 10 minutes but Ibrahimovic is one of several high-profile names who are due in England's capital city on Saturday night.

According to Sky Sports News, heavyweight stars Wladimir Klitschko, Anthony Joshua and David Haye will all be in attendance, as will Lee Selby, James DeGale and Brook's long-time rival Amir Khan.

Film star Mark Wahlberg and members of the cast of Game of Thrones also have tickets for an event that has been dubbed as the biggest boxing event of 2016.

Golovkin's WBC, IBF and IBO belts will be on the line against Brook, who is stepping up two weight divisions to face the hard-hitting Kazakh.
