The Swiss star landed his first major since Wimbledon in 2012 when he walked away with his fifth Australian Open title to extend his Grand Slam record to 18 majors.
Amazing to think he dropped out of the world's top 10 in November last year, the first time since November 2002 he found himself in such a position.
He struggled with his fitness throughout 2016 and missed the French Open through injury, the first time since 1999 he has missed a Grand Slam event.
Federer took an extended break following knee surgery and began 2017 in remarkable fashion by firstly winning in Melbourne and then claiming back to back Masters 1000 titles in Indian Wells and Miami.
The 35-year-old announced that he won't play in the French Open earlier this month having missed the whole clay-court season in order to prolong his career and will instead prepare for Wimbledon.
