The Swiss extended his winning streak over the injury-prone Spaniard this year to four matches after beating the top-ranked Spaniard 6-4, 6-3 to win the Shanghai Masters on Sunday.
Federer converted three of his seven balls break during the meeting to rein in 16 the series of victories of the Spaniard, who has notably won the title last week at the China Open.
The Swiss 19-time grand slam victor, who still trails Nadal 23-15 in their head-to-head record, didn't face a break point and started and ended the match with service breaks.
Dimitrov sensed another opportunity in the fifth game of the third set, but Nadal survived the break point.
The two legends stand side by side after the match.
Shanghai: Roger Federer has heaped praise on Rafael Nadal, saying the current world number one is "too good a player" and it won't be possible for the Swiss to win all the matches against him in the near future.
Nadal had nearly blitzed through the field on his way to the final and was seeking his second title in China following his win in Beijing the previous week, but went down tamely 6-4, 6-3 to the Swiss ace on Sunday (15 October). "He's too good of a player", he added.
In spite of its successes in 2017, Federer does not believe that he will one day return to the threshold of respectability in these duels against Nadal. "I need to think about it. I started off very well and relaxed from then on". To be honest with you, you can't always win against "Rafa". "He played very fast and he played well". When somebody plays better than you, sport is not very hard. The Australian Open's decision to speed up the surface played to Federer's attacking instincts.
The eight-time Wimbledon champion's decision to skip the clay court season ensured Federer will be at full strength for the indoor fall season where he's played some of his most dynamic tennis. Nadal, 31, fresh from winning the US Open and China Open, groaned while lashing many of his shots; Federer was all quiet efficiency.
Cilic, bidding to reach the season-ending ATP Finals in London, grabbed the critical break in the sixth game of the first set on his way to a comprehensive victory.
It also proves Federer can cede Paris to Nadal and still challenge for the world No. 1 ranking by remaining committed to his attacking cause.
