Two sporting superstars came together in Melbourne on Thursday as Perth Glory ace Sam Kerr met tennis great Serena Williams.
Williams, a 31-time Grand Slam singles champion, is in the country for the upcoming Australian Open.
Kerr was able to meet with the American sporting legend at a promotional event for Nike.
The Perth Glory and Westfield Matildas spearhead sent social media into a frenzy by sharing a picture of the encounter on Instagram.
"When you meet the actual GOAT [Greatest Of All Time]," Kerr wrote.
Glory captain Kerr will be back in Westfield W-League action when she leads Perth at Newcastle Jets on Saturday.
The 25-year-old is due to return to Melbourne in March, when the Westfield Matildas take on Argentina at AAMI Park in the Cup of Nations.
