Responding to a question at his press conference at Indian Wells about how a match between Roger Federer and Bjorn Borg would have been, and how the Swiss will be regarded for his clay court abilities after his retirement, Rafael Nadal replied, "We cannot compare the different tennis moments.
Bjorn Borg was an incredible ruler, for a long time. It's really amazing what he achieved on hard, on the grass, on every surface. He was a great champion. "Roger Federer is also a great champion. He's a fantastic player on clay.
He reached the final five times at Roland Garros, winning one in 2009 (against Robin Soderling), and he made the semi-finals in 2005. I’ve never seen many players who have reached the finals of the Paris tournament for so many consecutive years.
This means that Roger is probably one of the best players in history on clay." ALSO READ Roger Federer in doubt for the BNL Internazionali d´Italia: ´I do not know if I will play in Rome´ John McEnroe: ´Serena Williams for US president!´
