Wawrinka believes Federer on course for number one

MIAMI, Florida: Roger Federer’s comeback from injury has been so successful that his compatriot Stan Wawrinka believes he can become the oldest world number one in history at the age of 35.

Federer beat Wawrinka in the final of Indian Wells on Sunday for his second win of the year following his triumph in the Australian Open - his 18th grand slam title and his first in four and a half years.

Compatriot Wawrinka believes that not only is Federer back in form but he is playing in a noticeably different manner that gives him a chance to return to the pinnacle of the rankings.

“He’s playing really well, what is different maybe is he is playing closer from the baseline, preferring, using less his slice, he is using more top spin, putting more pressure all the time, returning better that’s the difference I see,” Wawrinka said Tuesday at the Miami Open.

“For sure he has a shot for number one, he has just won the first Masters final,” “For sure he has a big shot,” he told reporters.
