How well do you know the top men's and women's tennis players?
Reuters' team of photographers at the Australian Open in Melbourne take around 4,000 images a day, but not all of them show the players' faces.
Can you identify these players by their trademark outfits, tattoos or hairstyles?
This former champion may have cut off his ponytail, but the headband has been a near consistent companion for almost two decades on tour.
This shirt-tearing Serbian owes much of his Australian Open success to a change of diet that left him with a lean physique to tackle the energy-sapping matches under the Melbourne sun.
This American has conquered all on a tennis court, and done it in style. The fashion designer's colourful outfits with distinctive prints frequently veer off traditional tennis attire making her an easily recognisable presence on court.
This power-hitting former world number one clubbed his way to an Australian Open title in 2009. Gone are the sleeveless vest tops that used to show off his bicep muscles but the bruising groundstrokes remain.
This Japanese baseliner can be identified by his distinctive accessories bag, featuring the names of world cities. He was beaten by Roger Federer in the fourth round of the men single's in Melbourne.
This American star is also a fashion designer with an eye for vibrant styles. She will compete in her second Australian Open singles final on Saturday, 14 years after her first.
This Swiss former champion has a quote from literary giant Samuel Beckett inked on his left forearm which reads: "Ever tried. Ever failed. No matter. Try again. Fail again. Fail Better."
This Briton, a perennial Australian Open runner-up, has a distinctive birth mark on his right calf and never takes to court without his protective ankle braces.

This British talent made a surprise run to the fourth round of the men's singles this year, beating home hope Bernard Tomic along the way. He sports a tattoo on his arm that reads "Every saint has a past, every sinner has a future".
This Frenchman with the distinctive afro hairstyle was knocked out in the quarter-finals of the men's singles this year. Still searching for his first grand slam title, he reached the Australian Open final in 2008.
This 31-year-old Russian won her second Australian Open women's doubles title in 2012 with compatriot Vera Zvonareva. She sports tattoos on her arms that read "Pain doesn't kill me, I kill the pain", and "Only God is our judge".
