Venus Williams has opened the door for a competitive return alongside sister Serena after a picture was posted of them training together.
The Williams sisters have won 14 Grand Slam doubles titles together as formidable partners with their final victory coming at Wimbledon in 2016. Venus, aged 42, is individually ranked outside the top 1,000 in the world and lost in the US Open first round in the singles competition.
She partnered Serena, for what could be the final time, in the doubles with the pair suffering a second round defeat as her sister bid farewell in emotional scenes.
