Roger Federer goes into the ATP Finals ranked third in the world, with Rafael Nadal sitting narrowly above Novak Djokovic at the top.
The Swiss veteran will be hoping that the Spaniard’s injury issues do not help his Serbian rival achieve victory.
The 38-year-old is the only man to have won the tournament six times during his career.
Federer lifted the trophy for the first time way back in 2003 and followed up with wins in 2004, 2006, 2007, 2010 and 2011.
Djokovic made his name at the tournament back in 2008 and won it again in 2012, 2013, 2014 and 2015.
