It has been a tough past month for the 37-year-old, with Djokovic making unwanted history after suffering another early exit at Indian Wells.
This drop in form dates back to the Australian Open, where Djokovic was booed off the court after retiring from his semi-final against Alexander Zverev.
Djokovic has not always had the crowd on his side over the years, while his biggest rivals Federer and Nadal were fan favourites across the globe.
