Defending champion Rafael Nadal cannot face Novak Djokovic until the final at the French Open, having been kept apart in the draw.
Rafael Nadal’s bid for a 12th French Open title has seen him put in the same half of the draw as Roger Federer at Roland Garros.
The men’s draw was conducted on Thursday and Nadal, who has only twice lost at the only clay-court major, will begin his campaign against a qualifier.
Two further qualifiers are potential second-round opponents, with Kei Nishikori the first possible top-10 seed he could face in the last eight.
Twenty-time grand slam champion Federer, Stefanos Tsitsipas – who knocked Nadal out of the Madrid Open – and 2015 winner Stan Wawrinka represent potential semi-final opposition.
Potential #RG19 Quarter-finals
 Novak Djokovic vs.  Alexander Zverev
 Dominic Thiem vs.  Juan Martin del Potro
 Stefanos Tsitsipas vs.  Roger Federer
 Kei Nishikori vs.  Rafael Nadal

Nadal and Federer – who opens against Lorenzo Sonego – will consequently not meet either world number one Novak Djokovic or dangerous clay-court star Dominic Thiem until the final.
Djokovic will begin against Hubert Hurkacz and a crunch quarter-final could await, with Alexander Zverev in that section of the draw, along with Monte Carlo Masters champion Fabio Fognini.
Thiem lost in the final to Nadal last year and faces wildcard Tommy Paul to start.
