The 2021 Fifa Club World Cup, featuring the champions of different continents, kicks off on Thursday in the United Arab Emirates.
European champions Chelsea are among seven teams from six confederations competing to become the club world champions in Abu Dhabi.
The annual event was due to take place in December 2021 before Japan, the original hosts, pulled out in September because of Covid-19 restrictions in the country.
Fifa has been criticised for rescheduling the 18th edition of the Club World Cup while the Africa Cup of Nations is taking place.
Former Egypt international Mido said in November the new scheduling was "disrespectful" to Africa.
