Serena Williams returned to tennis after a year away with a doubles win at the Eastbourne International on Tuesday and while the American great reaffirmed her love for the game she said her future on the circuit remains uncertain.
The 23-times major champion had not played competitive tennis since limping out of her first-round match at last year's Wimbledon in tears due to a leg injury, and the 40-year-old said there were times when she doubted she would ever compete again.
