"If you'd asked me that a few years ago, I'd have said no," Becker was quoted as saying by AFP. "But this year he (Nadal) has returned to his top form and now has 13 titles to his credit."
"He's 27 and doesn't intend to stop there. He's capable of getting more," he added.
"Nadal is a great competitor. After all that happened to him last season (a long lay-off with a left knee injury) to return and have the success he's had this year in becoming world number one again is almost a miracle."
Nadal has won 13 Grand Slam titles till date, and don't be surprised if the Spaniard walks away with a few more, as he has been in his prime these days.
