This competition was first contested in 2000 as the FIFA Club World Championship.
It was not held between 2001 and 2004 due to a combination of factors, most importantly the collapse of FIFA's marketing partner, International Sport and Leisure.
Since 2005, the competition has been held every year, and has been hosted by Brazil, Japan, the United Arab Emirates and Morocco.
If Flamengo win they will become the fourth Brazilian club to take the trophy, following the successes of Corinthians, who won in 2000 and 2012, Sao Paulo, the 2005 winners, and Internacional, who won the following year.
Liverpool will seek to become the second English winners, following Manchester United in 2008.
Real Madrid have won the trophy on four of the last five occasions, with the 2015 final being won by Spanish rivals Barcelona.
