Rafael Nadal still trying to find best form as he sets up quarter-final with Andy Murray
Pair haven't played each other for more than two years

Rafael Nadal continued to search for his best clay form, surviving a shaky start on Thursday to reach the quarter-finals of the ATP-WTA Rome Masters and a date with Andy Murray.
The top seed beat Russian Mikhail Youzhny, winning 12 of the last 13 games in a 6-7 (4/7), 6-2, 6-3 win which took almost three hours.
Murray and Nadal have not played each other for more than two and a half years, when Murray beat the Spaniard in a 2011 Tokyo final.
Less than 24 hours after being severely tested by Gilles Simon, Nadal found himself in trouble against Youzhny, who last won a set against the world number one back in 2008.
After spending 73 minutes in losing the opener, Nadal finally found enough form to take the victory at a tournament where he is looking to win for the eighth time.
