#5 24 consecutive wins in tournament finals
From 2003 Vienna to 2005 Bangkok, Federer reeled off a record 24 consecutive wins in tournament finals.
That streak looked good to get extended to 25 as the Swiss maestro took a two set lead in the title match of the 2005 year-end ATP Finals (then called the Tennis Masters Cup) against David Nalbandian.
The Argentinian won the next two sets and went ahead by a double break in the decider, but Federer served for the title at 6-5 - before Nalbandian broke back and won the ensuing tiebreak to end the Swiss' stunning final record.
A win against Nalbandian would have also allowed Federer to emulate John McEnroe's 82-3 win-loss record set in 1984 for the best win-loss mark in a ATP season.
Among active players, Nadal won 14 consecutive finals from 2005 Monte Carlo to 2006 Roland Garros while Djokovic has 10 consecutive final triumphs - from 2015 US Open to 2016 Rome.
