New Delhi: World number one Novak Djokovic on Sunday crushed Roger Federer to win the ATP World Tour finals in London.
The Serb has been in sensational form in 2015, winning three Grand Slams.
Soon after winning his fourth consecutive season finale title, Djokovic 'revealed' the secret of his success this past year.
The 28-year-old is credited his wife for inspiring him and making 2015 the best year of his life.
The amount of effort Djokovic puts in to his game, from his dietary discipline to training methods, is well documented.
But this incredible gesture from Nole once showed why he is considered to be just as impressive off the court.
Thank you to my wonderful wife for inspiring me everyday...you made this the best year of my life pic.twitter.com/6VMrMAh65Z
