RIO DE JANEIRO, Brazil -- Rafael Nadal is back -- and its all about his back. Pittsburgh Pirates Gear . Top-ranked Nadal injured his back warming up for the final of the Australian Open almost three weeks ago, eventually losing against Stanislas Wawrinka -- a match he was an overwhelming favourite to win. Nadal has practiced little since then, getting treatment at home in Mallorca. His first test comes in next weeks Rio Open, a new stop on the ATP Tour. "Well have to see how it goes," he said Friday. "I hope I can tolerate it." Nadal knows the clock is ticking. He made a comeback last season from a left knee injury, which kept him out of the 2012 London Olympics. Hes won 13 Grand Slams. Hes one behind Pete Sampras, and hes closing in on Roger Federers record of 17. Hes sure one got away in Australia. "In Australia I lost a good opportunity to add another Grand Slam," Nadal said. "It didnt happen. The opportunities are not infinite. They have an expiration date." Nadal has played more than 11 years as a professional, perhaps sustaining some injuries because of his big swings and attacking temperament. "I heard a lot of times in my career that I will have a shorter career because of my style of game," he said. "I really think its something that will not happen. If I stopped today, I already will have more than 11 years on tour." The Spaniard said hes still motivated, positive about the 2014 season. "I cannot predict the future for how long I will be here competing well," he said. "I cant say when thats going to end. The only thing I can say is today I feel happy about what I am doing. I am feeling motivation mentally to keep playing, to keep competing well." Hell be 30 when the 2016 Rio Olympics begin. He called winning gold in the 2008 Beijing Olympics "one of the best experiences" of his career. "It was a very hard moment for me when I made the decision not to play the Olympic Games in London," Nadal said. "After that, I always say my goal is to arrive to the 2016 Olympic Games here in Rio."

The goal brought Bayern coach Pep Guardiola racing down the touchline to celebrate with Boateng. "We know how difficult the group is and a victory for the start is very, very important for us," Guardiola said.

Schalke levelled in the 62nd when Fabregas lost the ball and a counterattack ended with Netherlands forward Klaas-Jan Huntelaars goal. "A good point for them.
