Serena Williams hints she will make return to tennis at Wimbledon

• American has not played professionally since last summer
• Williams's long-time coach now working with Simona Halep

Serena Williams has hinted that she will make her return to tennis at this year's Wimbledon.

The 23-time grand slam champion has not played professionally since last year's Wimbledon, where she withdrew early in her first-round match against Aliaksandra Sasnovich due to a hamstring injury. The injury also caused her to miss the US Open, and she chose not to travel to the Tokyo Olympics. She did not play at this year's Australian Open after saying she was not happy with her level of fitness.
