Hingis issues warning to Clijsters

Martina Hingis admits Kim Clijsters needs to exercise caution when returning to the court after coming out of retirement. Clijsters stunned the tennis world in September when she announced her intention to resume her professional career, seven years after walking away from the sport for a second time. She was initially planning to come back at the start of next year, but a knee injury has delayed her return date. The Belgian was already a mother when she first retired in 2007, and since leaving the sport in 2012, she has had two more children. Hingis believes Clijsters needs to be careful when coming back into professional sport, particularly in regards to injuries and recovery. “Having had three children, 36 years old, I was surprised, yes,” he said. “She might be playing great but it’s also the recovery. For me, even playing doubles, that was the hardest part. The week in, week out. I already heard she’s injured. “I didn’t want to say anything bad because it’s great she wants this challenge but I think it’s not easy. Being a mother now and having had a couple of comebacks, I don’t think it’s as easy as people sometimes think.”
