Abu Dhabi – There is a question mark behind Rafael Nadal’s appearance in the first tennis Grand Slam tournament of the year. The 35-year-old Spaniard, who returned to the field this week at an invitation tournament in Abu Dhabi after a four-month break due to a foot injury, still has certain doubts about the trip to the Australian Open. “To be 100 percent honest, I can’t guarantee it. I have to talk to my team about it,” said Nadal.
